Question

Which of the following is a valid JavaSript statement?
a. If (x = 5) x == 2 * x;
b. if (x = 5) x =2* x;
c. if (x == 5) x == 2 * x;
d. if (x == 5) x = 2 * x;​

Answer 1

Answer:

D

Explanation:

A and B are not valid because you cannot use "=" as a comparator (you must use "==" or "===").

C is not valid because the expression after the conditional is not a statement (it uses "==" instead of "=")

Answer 2

It is D if (x == 5) x = 2 * x;​
