Type Conversion

Convert between strings and numbers explicitly.

type_conversion.js

const text = ;
const num = Number(text);
const back = String(num);
const doubled = num * 2;

console.log("num=" + num);
console.log("back=" + back);
console.log("doubled=" + doubled);

const text = ;
const num = Number(text);
const back = String(num);
const doubled = num * 2;

console.log("num=" + num);
console.log("back=" + back);
console.log("doubled=" + doubled);

const text = ;
const num = Number(text);
const back = String(num);
const doubled = num * 2;

console.log("num=" + num);
console.log("back=" + back);
console.log("doubled=" + doubled);

type-conversion `Number(...)` turns a numeric string into a number and `String(...)` turns a number back into text, so values can be used in the right context.
