Introduction to JavaScript in the first chapter1. A brief history of JavaScriptInvented in 1995 by Netscape's Brendan Eich, JavaScript was originally designed to handle some input validation operations on the client, and since then became a feature of common browsers, and today's use is not limited to simple data validation, but ability to interact with almost any aspect of the browser window and its conte

It responds to the user in an event-driven manner. Event-driven refers to the action that occurs when an action is performed on the home page, called an "event."

This article summarizes some methods I have found in JavaScript programming to improve the JavaScript running performance. In fact, these experiences are based on several principles and loops are a very common control structure, most of the things depend on it. in JavaScript, we can use three loops: for (;), while (), and for (in). in fact, in these three loops,

Netscape's bets are finally rewarded, and JavaScript has become an essential component of the Internet.Three pillarsBecause JavaScript 1.0
