Fortunately today, all Internet browsers have provided a JavaScript reading option and enabled by default. Keep in mind that many features on web pages are JavaScript dependent and will not work properly if it is disabled. JavaScript is now everywhere on the web and everyone uses it even though developers feel much more comfortable with it.
Simplicity
Currently, therefore, developers use this situation of omnipresence as an excuse to choose JavaScript. It has one of the simplest bases of this language. Its architecture is the most accessible there is. This is also one of the reasons for apprentice programmers to convince themselves of the simplicity of JavaScript and, above all, to easily become familiar with it. Its learning is simple and quick because in just a few minutes, beginners can see the results of their efforts in a positive way. No need to be scientific, you just need to understand the manuals available to everyone. It is also this simplistic side of JavaScript which makes it one of the most chosen languages at the start of programming training. But, even so, simple is far from saying inefficient. No ! Javascript is so far its power and its peak.
The developer and JavaScript
By running the code one line or a progressive function, you can observe changes in the data and on the page to understand exactly what is happening. You can also modify the data values used by the script, and you can even modify the script itself. Why is this variable value 20 instead of 30? Why does this line of code seem to have no effect? Why is this indicator true when it should be false? Every developer faces these questions, and steps through code to find out. After setting the breakpoints, return to the page and use it normally until a breakpoint is reached. Focus moves to the dev tool or devtool sources panel, and the breakpoint is highlighted. You can now selectively run the code and examine its data, step by step.
Popularity
Javascript is becoming one of the best known and most used languages for all its reasons. Its multiplatform Javascript nature and its omnipresence on the web remain one of these assets. And without forgetting its lightness and accessibility, it is completely normal that web developers come together to choose it. It is entirely capable of changing the world of the web as Google does with natural referencing. JavaScript has something to offer the professional. Its power is currently undeniable and it has even become an essential tool for programmers and SEOs.
