Personal Summary:1.webassembly Introduction: Webassembly is an efficient, low-level bytecode for developing network applications. Allows languages other than JavaScript (such as C,c++,rust and other) to be used in Web applications to write applications and then compile (early) WebAssembly.This is the sixth chapter of how JavaScript works.Now, we'll dissect how WebAssembly works, and most importantly, its pe
Javascript rather than hate it. It is a one-night stand product of C language and Self language. "2. Class LibraryJS does not have the concept of Class. prototype is used to implement the inheritance mechanism. For programmers who are used to the class usage mechanism of Java and C #, it is not very easy to use. John Resig, author of JQuery, also provides a library. Class and extend can be used in JS.

The setTimeout and setInterval of JavaScript are two methods that can easily fool others' feelings, because we often start to think that the call will be executed in the established way. I think many people share the same feeling. For example
The Code is as follows:
SetTimeout (function () {alert ('Hello! ');}, 0 );SetInterval (callbackfunctions, 100 );
It is assumed that the greeting method in setTimeout will be executed immediately, because it i

Sometimes we need to trigger an event without returning a value during js writing, so we may need to write href = "#", which contains a location information. the default anchor is # top, that is, the top of the Web page. When you click this link continuously and quickly, the browser slows down or even crashes.
