The difference between actionscript and javascript_Basic knowledge

At that time, Netscape's JavaScript made it the leader in the browser war with IE. Then IE created jscript to respond to Netscape's JavaScript. In fact, jscript basically copied JavaScript. This is also something that Microsoft has been criticized for. jscript and JavaScript has some grammatical differences, but both are the same type of web development technology, and JavaScript is currently popular, and jscript is used less and less. In addition, the core of JavaScript is ecmascript, which is the same as the core of actionscript, so it will be easier to learn actionscript after learning JavaScript, and vice versa.
