Hello Folks π
What's up friends, this is SnowBit here. I am a young passionate and self-taught front-end web developer and have an intention to become a successful developer.
Today, I am here with a basic topic for my beginner friends and javascript revisers. Happy Reading!
In this article, I will be discussing a few methods to convert a string into a number.
parseInt()
const x = "5"
parseInt(x) // 5
You can easily convert a string to a number with parseInt()
. If you pass any word or a letter in parseInt()
then it will return Nan
- Not a Number
Number()
In JavaScript, the Number()
method converts the value to a number and if the value failed to convert then it will return NaN
.
const x = "5"
Number(x)
Plus (+) unary operator
const x = "5"
const num = +x
Using the +
operator alone before an element indicates a math operation and tries to convert the element to a number, and if it fails to do - it will return NaN
Thank you for reading, have a nice day!
Your appreciation is my motivation π
