, and is known as the JavaScript World Einstein, his "JavaScript language essence" is not suitable for beginners to learn. This book does not articulate, clear, and clear the core concept of JavaScript. But for more advanced learning routes, I'd suggest you look at Mr. Crockford's video.Also, don't learn JavaScript from websites like Codecademy, because even if you know how to write a bunch of small snippets of JavaScript code, you can't learn how to

the stacks of JavaScript online tutorials, which is the worst way to learn. It may be a bit of a success after you've seen countless tutorials, but it's really inefficient to learn a thing in a hierarchical way, and you'll get stuck frequently when you actually build a Web site or web App with JavaScript. In general, this learning approach makes it hard to know how to use language as a tool-as a personal tool.In addition, one might suggest starting with JavaScript in the language of JavaScript,

Just begin to learn programming, if just take a book desperately knocking code, it is very boring. If not very determined and perseverance may be easy to give up, there is no study of the steep slope of the course? So that we can learn some basic knowledge, such as the introduction of Kung Fu, tasted the sweetness, and then choose their favorite things to learn? The answer is yes, and the following sites will allow you to learn programming knowledge quickly and relatively easily and interestingl

This article is written to those who really want to program-those who are holding on and must make something really, rather than those who "Hear that programming is fun. In my opinion, these people are unlikely to really make a decent thing. 1.

used JavaScript library. You may have heard of other popular JavaScript frameworks, such as Mootools, YUI, and Dojo. You can regard them as a set of JavaScript auxiliary tools. When you use them, you are still writing JavaScript, but they are all very abstract JavaScript. It will make you get twice the result with half the effort.
