using parseInt function with JavaScript

parse-int.js

function parseIntTest() {
    var a = parseInt("5");
    console.log(`a: ${a}`)
    //variable a will have numeric value 5

    // this is a bug in some of the older browsers where
    // parseInt with '08' will return 0
    // if you are supporting older browsers, make sure you
    // mention second argument, the base for number system as 10
    var b = parseInt("08");
    console.log(`b: ${b}`)
    //variable b will have numeric value 0
    var c = parseInt("08", 10);
    console.log(`c: ${c}`)
    //variable c will have numeric value 8
}

parseIntTest();
