TIL ES2021 - plus(+) operator as an alternative parseInt & parseFloat

POSTED ON:

TAGS: javascript

You can use the + operator in front of any numeric string to parse it as a number.
It will return NaN if the string isn't numeric


// converts string to int
parseInt("20"); // result: 20
+"20" // result: 20.3

// converts string to float
parseFloat("20.3") // result: 20.3
+"20.3"  // result: 20.3
