7 reasons why every programmer needs to learn about JavaScript _ basics

Recently I've been talking to hiring managers about how hard it is to find a good programmer, and I've come to realize that programming languages are getting more and more heavy on JavaScript. This is especially true for Web developers. So, if you're a programmer, then you should learn JavaScript.

Demand

The main reason I'm saying this is that as JavaScript matures and Node.js programs become more viable, our demand for JavaScript programmers continues to grow. JavaScript has surpassed C # in the demand ratio, just below Java. If you look at a viable project on GitHub, you'll find that JavaScript is appearing more and more, even ahead of Java and C #. Finally, if you look at StackOverflow, you'll find that JavaScript is also active in the top layer.

Better pay

According to Sitepoint,javascript salary is higher than C #. Of course, Java's salary is still a little higher than JavaScript's today. But as the demand for JavaScript grows, you can foresee that its pay will definitely improve.

In GooRoo, there is a slight difference in the picture of compensation vs. demand rendering. While the need for JavaScript is obvious, it is clear that several smaller-demand languages pay more. I suspect this is because many companies still think of JavaScript as a language that any programmer will use. But when they realize that "any programmer can JavaScript" is actually "any programmer will only write crappy JavaScript code", it is also the time they experienced a painful lesson. Then the real JavaScript programmer needs to get into the cleanup left by the mess.

In StackOverflow, we saw a very detailed classification of developers over the past three years. When you last saw the "Technology in use" section, we found that if you call yourself a JavaScript programmer (which is assumed to be on the client), you get a lower pay than a C # programmer, but better than a Java programmer, But if you say you're a node.js programmer (full JavaScript), you'll get a second-highest salary. The only thing taller than Node.js is objective-c (I assume it will be, Swift).

JavaScript is becoming more and more mature

New JavaScript standards are released every year, and it is now clear that the number of syntactic sugars (syntactic Sugar) added to JavaScript is increasing every year. One of the features I'm looking for is the ability to use asynchronous and await keywords in my JavaScript code to eliminate the callback Hell (callback Hell).

The sooner you start learning JavaScript, the easier it is to learn. All the changes are gradual, just as browsers are constantly improving their ability to process JavaScript code. It can be foreseen that in the near future browsers will not only cache JavaScript files, but also cache the compiled versions of JavaScript files.

JavaScript programmers are more able to be entrusted with the task

About a year ago, when I was chatting with an old friend of mine, he mentioned that he was the only programmer in their group (about 20 programmers) to write JavaScript in such a way as to eliminate the pollution of variables to the global scope. This is just the simplest example. Many people call themselves JavaScript programmers, but they don't know the basics. So, JavaScript is promising.

And don't forget that many of the tools that support performance analysis and memory leaks are just getting started. If you have mastered these skills now, you will certainly be able to sell yourself better in the future.

If you are interested in this kind of thing, you can read some of the courses on Pluralsight. Just search for "JavaScript profiling."

An increasingly sophisticated framework

A new version of angular is under development, and Aurelia as a candidate. Commercial products such as Scencha's ExtJS. There are also node.js for server-side programming. Wait, wait. It's not too hard to develop actual applications with JavaScript. I'm sure I could just use JavaScript to write a desktop application that I can run, if I want to. Hey.

JavaScript is everywhere

JavaScript can be run on all major browsers of all main platforms, or on the server side of every mainstream operating system. Nowadays we need developers who know how to write the front-end in JavaScript when writing any major functions for the site. It doesn't matter what the backend code is written with--whether it's java,php,.net,node.js or something--but the client needs a JavaScript developer. In fact, many developers are still not aware of how powerful JavaScript is. I don't know if you are a member of these frogs. If you're really a great JavaScript programmer, then basically all the work on the server-side platform is up to the job. If you know more about these platforms, you can basically take office.

JavaScript is a compiled language

This may surprise you, technically speaking, JavaScript is a compiled language. This has two meanings. First, once the code is compiled, it may run at a speed comparable to any other executable file. Second, writing a tool for JavaScript is technically feasible and will create a binary file that does not have to be recompiled each time the code is loaded into memory.

How do you feel about that?

Of course, all of these are my views. Do you have any thoughts? Welcome to enlighten me.
