If/else Statements in JavaScript

In JavaScript, if/else statements are implemented using if and else keywords. The if keyword is followed by an expression, which must be enclosed in round brackets (). The body of the if statement is denoted using curly braces{}. This is also known as the scope of the if statement. The body of the if statement contains one or several statements which need to be evaluated under the specified condition.

In general, we have the syntax as,

1if (expression){
2    statement
3}

For the odd-even number example above, if-else statements in JavaScript will be written as,

xxxxxxxxxx

var x = 5

if (x % 2 == 0){

    console.log("x is even")

}

else{

    console.log("x is odd")

}
