The difference between ActionScript and JavaScript _ basics

Netscape's JavaScript at the time made it the top of the browser wars with IE, and then IE created JScript to deal with Netscape's JavaScript, and in fact JScript basically copied JavaScript, This is one of the things that Microsoft has been accused of, JScript and JavaScript have some grammatical difference, but both are the same kind of web development technology, and the current popular is that the use of javascript,jscript has become increasingly scarce. In addition, the core of JavaScript is ECMAScript, just like the core of ActionScript, so it's easier to learn about ActionScript after learning JavaScript, and vice versa.
