Why “0” is not equal to false in if condition in JavaScript ?

The reason behind this behavior is that JavaScript treats non-empty string as true. First, “0” is converted into its boolean value, by automatic type conversion which is true. Therefore, if statement executes. 

Example: This example illustrates why “0” is not equal to false in if() condition. 

javascript

// JavaScript script to demonstrate
// why “0” is not equal to false in
// ‘if’ condition

function GFG() {

    // Print type of "0"
    condole.log(typeof "0" );

    // Print boolean value of "0"
    condole.log(Boolean("0") );

    // Boolean value of "0" is true so
    // 'if' part will execute
    if("0") {
        condole.log("if part executed");
    }
    else {
        condole.log("else part executed");
    }
}

// Driver code
GFG();

Output:

string
true
if part executed
