How can I convert the elements of the array into another array?
let a = [2, 4, 0, 8, 9, 15]
and the result will be :
a = [[2], [4], [0], [8], [9], [15]]

Use Array#map to iterate the array, and wrap each item in an array:
let a = [2, 4, 0, 8, 9, 15]
const result = a.map((n) => [n])
console.log(JSON.stringify(result))

What type of nomenclature is "Array#map" supposed to be?

It's an old MDN way of naming methods, which you can paste to the location box in the browser, and it will find the article in mdn, instead of trying to get to the website.

You might be used to it, but you're educating others here.

let a = [2, 4, 0, 8, 9, 15];
let b = a.map((item) => [item]);

a = [2, 4, 0, 8, 9, 15]
console.log(result = a.map((n) => [n]))
b=[]
//you can try below also
for (i in a){
b.push([i]);
}
