Client-side scripting is necessary to overcome the difficulties faced by users. It saves the user time. It also reduces the load on the server. In server-side scripting, the server computer receives data from users and performs different actions. For Example, if one is looking for tables and the system asks him to enter the desired number. There might be a case that he enters a number that is not available on the server-side. In that case, the server will look for it by performing different actions, and at last, it will show the result “Null.”
Client-side scripting ends all this and saves time. In client-side scripting, a computer is instructed to get only those number which is available on the server-side. Now, if a user enters a number that is not available on the server-side, the user receives a warning message indicating the entry of the wrong number. In this way, it saves time and reduces the load on the server-side.
By now, many programming languages have developed, and many will be developed. All the programming languages are developed with the intention of web and application development. They have all the tools required for web development. But the point is that, which language to learn and which not to learn?
