We have refactored the if statement code to run the else part if the statement age >= 21, returns false.

var age = 18 Ĭonsole.log('You are too young to vote') This is where the variation of if statement i.e. Sometimes we want to execute a set of statements if the condition checked in the if is false.

So, the statement 'You can vote in the election' will be printed in the console. Now, in the if statement we check whether age >= 21 and it is true. In the above example, we initialize age to 22. var age = 22 Ĭonsole.log('You can vote in the election') The if statement in it’s a standalone avatar, will run a set of the statement contained inside its curly brackets to run if it evaluates to true. JavaScript supports the following form of if…else statements – These conditional statements are an essential part of programming as they have logic to execute two or more different set of statements. Just like any other programming language JavaScript also have conditional statements like if…else.

Then we go to the next else if part and check whether age >= 10 and it is false again.So, we just print the statement in else part i.e. Then we go to the next else if part and check whether age >= 15 and it is false again. Now, in the if statement we check whether age >= 21 and it is false. In the above example, we initialize age to 9.
