Using method sort() for sorting symbols in element of array

Question

I need to sort an element cinema of array arr by symbols unicode (in the output it must been like "aceinm"). I know that in this case we need to use method sort(). But I do know how inject sort method for array element.

Please, help. Code below are not working.

Error: arr[1].sort is not a function.

var arr = ["cinema"];

arr[1].sort();
console.log(arr[1]);

Answer 1

If you want to sort your string, you can easily do this by splitting and joining the string.

"cinema".split ("").sort ().join ("")
// aceimn

Or, in your case:

arr[0] = arr [0].split ("").sort ().join ("")
// arr: ["aceimn"]

If you need to sort all strings in an array, use map ().

arr = arr.map (itm => itm.split ("").sort ().join (""))
