Unusual Unicorn
let string = "1";
let num = parseInt(string);
//num will equal 1 as a intvar myInt = parseInt("10.256"); //10
var myFloat = parseFloat("10.256"); //10.256let theInt = parseInt("5.90123"); //5
let theFloat = parseFloat("5.90123"); //5.90123let num = Number("123"); // 123
let num = Number("123.45"); // 123.45
let num = Number("blah"); // NaN (not a number)// try using parsInt(x)
// you can then use typeof(x) to confirm
var myString = "555";
var myInt = parseInt(string);
console.log(typeof myInt); // numbernew Number(valeur);
var a = new Number('123'); // a === 123 donnera false
var b = Number('123'); // b === 123 donnera true
a instanceof Number; // donnera true
b instanceof Number; // donnera false
