🍬Converting Numbers to Strings

In JavaScript, you can use the parseInt() function to convert a string to an integer. This function takes two arguments: the string you want to convert and the radix, which specifies the base of the number in the string. The radix is an optional argument and the default value is 10.

For example:

let str = '123';
let num = parseInt(str);
console.log(num);  // Output: 123

Here, the string '123' is converted to the number 123.

You can also use the parseFloat() function to convert a string to a floating point number. This function works in a similar way to parseInt(), but it can parse decimal numbers as well.

let str = '3.14';
let num = parseFloat(str);
console.log(num);  // Output: 3.14

It's important to note that the parseInt() and parseFloat() functions will only work if the string consists solely of a valid number. If the string contains any non-numeric characters, the functions will return NaN (not a number).

For example:

let str = '123abc';
let num = parseInt(str);
console.log(num);  // Output: NaN

In this case, the string '123abc' is not a valid number, so parseInt() returns NaN
