how to cut out a piece of a string with javascript jquery?

Question

I am having a string like below and i want to cut out the T with the time from it like below:

var string = '2021-05-10T08:00,2021-05-11T08:00,2021-05-12T08:00';

My new string should look like this:

var new_string = '2021-05-10,2021-05-11,2021-05-12';

How can i do that?

I tried with .replace function but the problem is that the time is not always 08:00

Break it into an array and process each chunk. map is a good function for this

 var string = '2021-05-10T08:00,2021-05-11T08:00,2021-05-12T08:00';
    var newstring = string.split(",").map(el => el.split('T')[0]).join(",");
    console.log(newstring);
