Convert string to integer in javascript
In this tutorial, we are going to learn how to convert a numeric string to integer/number in javascript.
First way
const a = "11";
console.log( + a ) // 11
if we just add the plus before the numeric string. it will convert as a number.
Second way
Number object helps us to convert the numeric strings into a number.
const a = "11";
const b = 4;
const aplusb = Number(a)+b
console.log(aplusb) // 15
Third way
Number.parseInt()
method takes two arguments first one is string and second one is base
const a = "11";
const b = 4;
const aplusb = Number.parseInt(a,10)+b
console.log(aplusb) // 15
In the above code, we used the base 10 because of decimal numbers.
Happy coding…
