This article is about what JavaScript is, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it with the editor.

What exactly is JavaScript? to put it simply, JavaScript is the only scripting language supported on all major browsers today, and this is the only use of early JavaScript. Its main function is to get data from the server and display it without reloading the page, greatly improving the user experience.

Through JavaScript, it is possible to develop Web pages into clients. Although the creator of JavaScript, as the only supported language in the browser, created it in only ten days, it also makes it very operable, much less difficult to get started than other languages, and can be developed and debugged on any browser without the need to install additional software. It is for this reason that JavaScript has a wide range of users, and naturally, the language has been gradually extended to areas other than browsers. In short, JavaScript is an interpreted scripting language that can be parsed by browsers. A scripting language is a language that can be executed directly without a compilation process.

Many people think that the front end is nothing more than that when they finish learning HTML, CSS, JavaScript, bootstrap and jQuery. Cut the page to write special effects, so easy. However, it is too young after all.

The hole at the front end is so deep. And those who say that no matter how the outside technology innovates, I will stick to the jQuery camp, will eventually be eliminated.

Ajax interaction is now widely used. When you still indulge in the delicacy of jQuery operating dom, you find that in fact, the background MVC development mode has been gradually replaced by RESTful development mode, the front end also has its own MVC, and then because of layering to learn backbone, and then because of operating data structures to learn underscore, and then there are equireJS (AMD) / seaJS (CMD) / webpack (commomjs) and other series of messy, let you run.

The front end has a long way to go, and there are as many frames as Mao, but not all of them need to be learned. As long as you master the core JS of the front end, you can be very calm. As long as you have a solid foundation in JS and end up with some background thinking, no matter what framework it is, it will be easy to learn.

The core of the framework should be its architecture and design. When you understand the principle of implementation and give you time, you can also draw a cat according to the tiger.

JavaScript is one of the comprehensive, simple, results-oriented web development languages. It makes data processing and calculation possible, and helps add visual effects to the screen. It is a language for client-side and server-side applications. It has a wide application prospect in the future. In 2016, JavaScript ranked second in the world in terms of programming language salary, with an average salary of US $9000, and its job demand was even as high as 17%.

JavaScript is a very popular programming language, and according to the Bureau of Labor Statistics, the future opportunities for web developers will be favorable by 2024. By 2026, the employment rate of web developers will grow to 13%, much faster than the average occupation. There were 162900 web development jobs in the United States in 2016, and that number should grow to about 184200 by 2026. Mastering JavaScript will go a long way.

JavaScript is one of the most popular scripting languages in the world, and JavaScript does not require that the user must be a programmer like other languages. In fact, many non-programmers also use JavaScript, and JavaScript is so powerful that it is used by millions of web pages to improve design, validate forms, test browsers, create cookies, and more.

As an interpretive scripting language, JavaScript is not only a necessary basis for front-end learning, but also carries the role of transition from basic to high-level framework.

The above is exactly what JavaScript is, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
