Which of the following jа vascript statement is to compare if num is 2 or 5, if yes, increment num by 1?

if (num==2 || 5)

num = num + 1;

if (num==2 || num==5)

num = num + 1;

if (num=2 || 5)

num = num + 1;

if (num==2 || num=5)

num = num + 1;

Hi!

The following jа vascript statement compares if num is 2 or 5 and increment num by 1 if true.

if (num==2 || num==5)

num = num + 1;

Explanation:

The operator = = is used to compare if the operands are equal.

The operator || is OR.

If at least one of the operands is true then return true. If all operands are false returns false.

if (num==2 || num==5) / / if num is equal 2 or if num is equal 5

num = num + 1; / / adds 1 to num.
