how to split on character in front of delimiter javascript code example

Example 1: string to array javascript

// If you want to split on a specific character in a string:
const stringToSplit = '01-02-2020';
console.log(stringToSplit.split('-')); 
// ["01", "02", "2020"]

// If you want to split every character:
const stringToSplit = '01-02-2020';
console.log(Array.from(stringToSplit));
// ["0", "1", "-", "0", "2", "-", "2", "0", "2", "0"]
