Speed

Google's V8 JS engine allows us to better execute JS code on both the client side and the server side, which provides a foundation for complex JS programs. We can now send hundreds of KB of compressed JS code to the client, and we can expect the client to execute the code smoothly.

In addition, JS is very easy to write and test. Write-save-refresh, you can see the effect in three simple steps, which is faster than any other development environment. We now also have a webkit console and debugger that can help us debug our code easily. I've also been trying to use Jasmine for unit testing recently.

JS is a very lightweight language without a large number of complex reserved words and a variety of complex data types. JSON has become a popular data transmission format. JS is also the native language of Web browsers, and there is a lot of tool support that requires almost no installation.

Maybe the authors of the JS framework want to keep the code as concise as possible, or they just default that things should be kept simple. I find that all JS frameworks are not very intrusive and do not have to write code in the agreed format like Rails,Rjango,CakePHP. The code of popular JS frameworks such as jQuery, Underscore.js, and Backbone.js is fully readable and focused, and their designs can be integrated with each other.

Plasticity

Deleting code is a happy process because it reduces complexity, fixes bug, and reduces the amount of code. So I enjoy the process of deleting the junk code I wrote. Due to the redesign of the page or changes in requirements, the foreground code naturally has a short life cycle. Modularity is a natural attribute of browser-side JS, which allows me to ReFactor a component without having to mess up all the code.

At this point, the study of "what are the advantages of JavaScript language" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
