JavaScript is very popular among programmers, and they get a lot of help from this language in order to create different programs, the reason for its great popularity is that there are various features in this language that can be used to achieve the main goal, so that it causes the user to have a better user experience while using the program or site which is created by using this language, as we have mentioned above, in this program, there are various possibilities that can be used by users in order to help them achieve the desired results in various fields, as a result, it is necessary to review the points related to each one, so that you can get help from each of them in the right place and time.In the following, we are going to review two of the features that exist which you can use in order to improve the quality of the content, but before that, we need to give a brief explanation about JavaScript.
What is a JavaScript programming language?
It is one of the programming languages through which the content of a web can be converted from static to dynamic, which enables the user to interact more with the web and programs which are created with the help of this language.
If ... else in JS:
The if / else statement causes a block of code to be executed if a predetermined condition is specified, and if another condition is not met, another set of code can be executed.
In this language, we have the following conditional statements:
- Use if:
You can use it when the condition which you set is correct and after checking that condition the code can be executed.
- Use else:
You can use else to specify a block of code to be executed, in a case that the same condition is incorrect.
- Use else if:
It is necessary to use it when the first condition you have set is incorrect, and it is necessary to execute the block of code after checking the second condition.
it refers to the main page of the application, to these logos and pages that reject the beginning of the path. Application applications are displayed called splash screens . Splash screens are actually a page that is displayed to users for a certain period of time at the beginning of launching applications, which includes the logo for the application , the manufacturer or ... This page is actually an activity that includes a special logo or emblem that is displayed for advertising and introduction to users at the beginning of launching the application and is also determined for this activity to be displayed for a certain period of time and then disappear and go to the main page Transfer the application.
What are splash screens?
In fact, splash screens are pages or activities that appear for a while after launching an application and can even include an audio file. It is better to choose the audio file and video file to be placed on the splash screen to be relevant to your wishes. You can do ads and introductions in the splash screen and put them in the view of users so that users can see them.
How to create splash screens
1- Create a new project with API 10 and choose the name SplashScreen as desired.2- The activity used in this training is Empty Activity.3- After creating the project, our project has an activity called MainActivity. We need to create another activity and assign one of them to the splash screen.4- We create a new activity and assign it to the splash screen; we also assign the MainActivity to the main page of the application.5- We create a new activity of Empty Activity type called SplashActivity, which is the desired name.6- Java class and active xml file are added to the project.7- In order to be able to create a splash screen to be displayed to users on the first page for a while when launching the application, we must use the Handler class.8- We update the Handler class.9- The class must be imported.10- To determine the stop time, we use the postDelayed method.11- The first parameter of this method is Runnable and the second parameter is the desired time, each of which must be entered in milliseconds.12- New Runnable and select the first option, by doing this, Android Studio will automatically create the run method.13- The code that should be in the SplashScreen.java class is as follows:
The number of cyber-attacks is increasing day by day , and the main reason of it, is that profiteers can earn significant income through this way, and the number of people who do their daily work through internet is increasing as well, so there is lots of important information in the systems of different users that can be very attractive for hackers due to the fact that they can make a lot of money through them.Every day, many reports of various attacks on users’ systems and organizations is being shown, which make the users more worried about their cybersecurity, so all the users are trying to be able to withstand these cases and maintain the security of their system , the first step in order to stand up against any threat is to know them as good as possible, therefore we will briefly explain the different types of security threats in the following in order to make you aware of them to some extent and prevent the side effects of such attacks on systems.It should also be noted that there are cybersecurity experts who can help a lot in this field and prevent hackers from inflicting irreparable damage on various organizations and users in various ways, hackers may have different goals, and as a result, they try various ways of hacking to achieve these goals.
What is hacking?
In simple terms, hacking is any action that can be used in order to access information in various systems without users’ permission and ultimately abuse that information to achieve their goals, there are different types of hackers , each of which have different personalities and also different goals, including red hat, black hat, pink hat, green hat hackers and so on.
What is security?
Security is considered as any action which is taken in order to block the ways of profiteers, so that they cannot access the available information without user’s permission, which is so important.
What are the cyber security threats?
Cyber security threats are considered as any threats that ultimately cause different people with various purposes in order to gain access to existing information and disrupt the function of systems, these threats may be carried out by different people, among which we can mention hackers, terrorist groups, etc., each of whom has different goals.There are many reports of cyber attacks every year, which ultimately lead to the disclosure of highly sensitive information which cause damage to various organizations and individuals, also if hackers can access the organizational system which communicates with different customers, they can eventually access the information of each customer that cause huge damage to the organization due to the fact that it is so hard to rebuild customers trust, after accessing the information of different customers, attackers can use the obtained data to access their user accounts or financial accounts which is so dangerous.
What are the different security threats?
There are several types of security threats which we are going to mention below.
- DoS attacks:
DoS, which stands for denial of service, is a common threat that may affect various systems, and as a result of this attack, the computer will no longer respond, in DDoS attack , which stands for distributed denial of service, the attack occurs from a computer network and eventually causes the user to disconnect from the Internet and various networks.
Having access to the system and information of individuals may be done through different ways, each of which has its own principles but in all of them, the final goal is gaining access to users’ information, and as you know, because of the increasing number of hackers and due to the fact that they prefer to use different methods in order to infiltrate systems, users are concerned about the security of their systems , as a result, they are trying to increase their awareness in this field to resist various hacking methods.There are different ways to steal information from users, one of which is through infected links, in this method, hackers put infected links in different places such as ads of various sites, emails, messages, etc., and finally users may to click on these types of links due to lack of awareness and finally provide their information and system to various hackers.
What would happen if someone accidentally clicks on a suspicious link?
If users inadvertently click on infected links, they will eventually provide their system as well as its information to hackers, and hackers can easily use this information in order to achieve their desires.
What should we do with infected links?
- The Internet may be full of infected links, so it is necessary for all users to raise their awareness about this type of hacking method and be able to detect this type of link in order to minimize the possibility of encountering them in the system, these types of links may be sent to you by phishing emails , so you should keep in mind this possibility, and you shouldn’t open emails which are not from reputable sources in any way, you may be wondering what are the signs of spam emails? These types of emails usually have a URL address which is similar to a reputable company’s email address and usually contain a message that arises your feelings such as fear, anxiety and so on, so it is likely that you click on it without thinking properly.- After viewing the links that seem suspicious, do not open them at all and delete them in the first step in order to reduce the possibility of various threats entering your system.- If you see this type of infected links on various sites, you can contact the site administrator and report it to him/her, because infected links which may endanger system as well as essential information of different users on their site, by doing so, you can also help other users not to click on these links.- Despite observing all the security issues and raising awareness about infected links, it is still possible to click on these infected links accidentally , at that time it is necessary to take the needed actions by thinking properly and without being afraid of anything, as a result, hackers cannot achieve their goals.
JavaScript programming language has many fans and many programmers try to use it, and with the help of this language you can give the user the possibility to interact more with existing content, there are several features in this language that need to be fully mastered by programmers who want to use this language in order to be able to achieve the best possible results by using each of the available features in the correct time and place, one of the facilities that exists in JavaScript is its libraries, which allow the programmer to be able to code at a very high speed, one of these popular libraries is called jQuery, in this article we are going to deal with adding and creating animation in it and also the way to stop it.

There are various features in jQuery, one of which is that you can use animation to make the existing content more interesting, which we will discuss in the following, this process is very common among different programmers , and in fact they use the animate () method to create their own animations, in this case, there are various parameters that can multiply the impact and beauty of an animation, one of which is the speed parameter, which can be adjusted to specify the duration of the effect to your liking.In order to be more aware of this issue, it is necessary to pay attention to the following example.
<p> By default, all HTML elements have a static position, and cannot be moved. To manipulate the position, remember to first set the CSS position property of the element to relative, fixed, or absolute! </p>
</body> </html> The result of the above example will be that after clicking the Start Animation button, the 100x100 square which we have determined its properties to move from left to right, one thing you should keep in mind while using different animations is that it is possible to change several features at the same time while executing the command, for instance in the example which have been mentioned above you may want to change the size of the square that was 100 x 100 at the beginning of the animation while move from left to right.
<p> By default, all HTML elements have a static position, and cannot be moved. To manipulate the position, remember to first set the CSS position property of the element to relative, fixed, or absolute! </p>
