Control structures
JavaScript has a similar set of control structures as the C and Java languages. Conditional statements are supported by if…else
and switch
. Loops are supported by while
, do…while
, and for
constructs.

The first conditional statement we will take a look at is the if…else

or another script just in case the condition is false
(else
):
var num = 0; if (num === 1) { console.log("num is equal to 1"); } else { ...
