JavaScript (+ +) increment operator

Source: Internet
Author: User

The increment operator adds 1 to its operand and returns a numeric value.

The increment operator is used in two ways:

(1). After use, the operator is behind the operand (such as x + +), then the value is returned before incrementing.

(2). Before the operator is in front of the operand (for example, ++x), the value will be returned after incrementing.

code example:

var x = 1;console.log (x + +); Console.log (×);

The back-use is to return the value first and then increment the calculation.

var x = 1;console.log (++x); Console.log (x);

The original text can be found in the JavaScript (+ +) increment operator section.
