如何从字符串中分隔数字和算术运算符？

Question

I have a string I need to read it and divide it to numbers and operations for a calculator.

For example: if the input is "22*432+33"

I need to console to take the string as whole and add the numbers in an array till it find operation signs and push the operation sign in another array so the output result:

numbers = ["22", "432", "33"];
operations = ["*", "+"];

The language I'm using is javascript I know the question may be board but I'm trying to solve it for a week with no success.

One of my fails attempt:

 var numbers = []; var tokens = ["+", "-", "/", "*"]; var textfield = "22*432+33"; for (var i = 0; i <= textfield.trim().length; i++) { if (tokens.includes(textfield[i]) == false) { numbers.push(textfield.split()); } } console.log(textfield); console.log(tokens); console.log(numbers); 

The output result:

You can split your input into digits and non digits.

 const input = "22*432+33"; const numbers = input.split(/\\D/g); const op = input.split(/\\d/g).filter(Boolean); console.log(numbers); console.log(op);
