i'm having trouble to get demanded answer

the question is

Create a function called forEach that takes two inputs:

- an array of numbers (a list of numbers)

- a 'callback' function

forEach runs the callback on each element of the array (updates the array passed in). forEach does not return anything. (8 pts.)

myarray = [2,3,4]; forEach(myarray, increment); console.log(myarray); // should output [3, 4, 5] (3 pts.)

so i made,

const increment = (x) => x + 1; // increment function. i must use the arrow function here.

function forEach(array, callback) {

for (let i = 0; i < array.length; i++){

callback(array[i]);

}

}

myarray = [2,3,4]; // should output [3, 4, 5] (3 pts.)

forEach(myarray, increment);

console.log(myarray);

but i still get the answer [2,3,4] not [3,4,5]

means increment function not used and answer not changed.

i need to implement the foreach.

please find explain where my problem is with the code

and please give the correct code and result. thank you
