Javascript: remove quotes from string of comma separated numbers

Question

I have a string

var s = "2,4,6,8,10"

I need output 2,4,6,8,10

Convert this string to int? Is this at all possible?

Answer 1

You mean to turn a string of numbers to an array of numbers? something like this:

 var s = "2,4,6,8,10"; var numberArray = s.split(',').map(i => +i); console.log(numberArray);

Note: changed it to from Number(i) to +i , simpler and cleaner imo

Answer 2

You can split the string by commas and then parseInt each string and get an array of numbers.

 let s = "2,4,6,8,10" let splitted = s.split(','); console.log(splitted); let parsed = splitted.map(x => parseInt(x)); console.log(parsed);

Answer 3

You can convert it into an array of numbers:

 let s = "2,4,6,8,10"; s = s.split(","); s.forEach((i, index) => { s[index] = parseInt(i); }) console.log(s)

Answer 4

I believe you are looking for something like this.

1. split the string into substrings which each contain one number

var arrayOfStrings = s.split(",");

2. convert these strings to numbers

var arrayOfNumbers = arrayOfStrings.map(s => parseInt(s))

3. log the array of numbers

console.log(...arrayOfNumbers)

combined

 var s = "2,4,6,8,10" console.log(...s.split(",").map(item => parseInt(item))); console.log("or") console.log(s.split(",").map(item => parseInt(item)));
