Javascript Conditional Statements

There are two conditional statements in JavaScript: if and switch. The if statement allows the program to choose one of two alternatives, based on some predefined factor.

If statement: It is used to interrupt program flow for some condition.

var num = 10;
                if (num < 20) {
                    alert(num + " is less than 20.");
                }

If - Else: It is used to interupt program flow for some condition but instead of satisfying for one, it will also check for second condition.

var num = 10;
                if (num < 20) {
                    alert(num + " is less than 20.");
                }
                else {
                    alert(num + " is greater than 20.");
                }
