This article introduces the knowledge of "how to apply the JavaScript assignment operator". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

In the JavaScript program, if you use the equal sign (=) of the assignment operator in the if conditional statement, it will produce an error result. The correct way is to use the two equal signs of the comparison operator (= =).

The if conditional statement returns false (as we expected) because x is not equal to 10:

Varx=0

If (Xerox 10)

The if conditional statement returns true (not what we expected) because the conditional statement execution assigns a value of x to 10 and 10 to true:

Varx=0

If (Xbox 10)

The if conditional statement returns false (not what we expected) because the conditional statement execution assigns x to 0 and 0 to false:

Varx=0

If (xan0)
