1. Multiplicative operators:

1) * Method of operation:

Infinity * 0 = NaN Infinity * Not 0 = Infinity or-Infinity

2)/method operator:

infinity/infinity = Nan 0/0 = nan n0/0 = Infinity

2. Relational operators:

< > <= >= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

3. Conditional operators, assignment operators, comma operators, and so on.

4. Statement:

If,do-wihle,while,for,for-in,with,break,continue,label.

5. Functions:

1) Understand parameters: any parameters in the function are actually stored in the arguements[] array.

2) without overloading, it will perform all

Summary: JavaScript syntax and C language and similar, so it is relatively simple to learn, but in some comparisons there are some differences.

A function that does not specify a return value returns a special undefined value.

There is no concept of a function signature in ECMAScript because the function parameter is passed as an array containing 0 or more values.

The ECMAScript function cannot be overloaded because there are no attributes for function signatures.
