How to change an array of objects to a string list with commas?

Question

I currently have an array in angular that I would like to change the structure of. Example array:

0: "Car 1"
1: "Car 2"
2: "Car 3"
3: "Car 4"
4: "Car 5"
5: "Car 6"

I would like to convert it to Car1,Car2,Car3,Car4,Car5 so that I can use the IndexOf() function for each comma.

What is your end goal exactly? Why do you need to use `indexOf` for commas? — Octavian Mărculescu, May 30 '22 at 07:57
Search after join. And before joining the items, remove the space (if necessary) with f. e. map. — derstauner, May 30 '22 at 07:59

[`.trim()`](https://www.w3schools.com/jsref/jsref_trim_string.asp) only remove the leftmost and rightmost space, but not the space in between words. – Yong Shun May 30 '22 at 08:52

let array = [ "Car 1" , "Car 2"  ,"Car 3" , "Car 4" , "Car 5"  ];
let newString = array.map(e => e.replace(/\s/g, '')).join(",")

Output will be - Car1,Car2,Car3,Car4,Car5
