The relationship between JavaScript and Java

Let's talk about JavaScript and Java in a simple and detailed way today.

The relationship between Lei Feng and Leifeng Tower, in other words: there is no relation between them.

But often there are a lot of beginners and even intermediate people think that they have a close relationship, this is very silent.

personally, if you do not distinguish clearly, the better the Java learning Beginner, JavaScript will learn the worse. It's hard to draw on a piece of paper because it's a good drawing on a blank sheet .
