I have the following basic js function:
function copy_array(arr) {
// copy array and return existing array
const cp = [];
for(let i=0; i < arr.length; i++)
cp[i] = arr[i];
return cp;
}
Is it possible to convert this into an arrow function, for example:
const copy_array2 = (arr) => {
// ?
}
Simply:
const copy_array2 = (arr) => {
const cp = [];
for(let i=0; i < arr.length; i++)
cp[i] = arr[i];
return cp;
}
const arr = [1, 2, 3]
const copy = copy_array2(arr)
arr[0] = 5
console.log(copy)
