Javascript split by numbers using regex

Question

I'm trying to come up with a regex that will do following. I have a string

var input_string = "E100T10P200E3000T3S10";

var output=input_string.split(**Trying to find this**);

this should give an array with all the letters in order with repetitions

output = ["E","T","P","E","T","S"]

See below. \d+ means one or more digits; filter (x => x) removes empty strings that can appear in the beginning or the end of the array if the input string begins or ends with digits.

var input_string = "E100T10P200E3000T3S10";

var output = input_string.split (/\d+/).filter (x => x);

console.log (output);

We can try just matching for capital letters here:

var input_string = "E100T10P200E3000T3S10";
var output = input_string.match(/[A-Z]/g);
console.log(output);

Another approach is spread the string to array and use isNaN as filter callback

var input_string = "E100T10P200E3000T3S10";

var output = [...input_string].filter(isNaN);

console.log(output);

You can use regex replace method. First replace all the digits with empty string and then split the resultant string.

const input_string = 'E100T10P200E3000T3S10';
const ret = input_string.replace(/\d/g, '').split('');
console.log(ret);
