Use for-of loop for array JS-0361
Anti-pattern
Minor
A for-of loop is recommended when the loop index is only used to read from the collection.
Bad Practice
for (let i = 0; i < arr.length; i++) {
console.log(arr[i]);
}
Recommended
for (const x of arr) {
console.log(x);
}
for (let i = 0; i < arr.length; i++) {
// i is used to write to arr, so for-of could not be used.
arr[i] = 0;
}
for (let i = 0; i < arr.length; i++) {
// i is used independent of arr, so for-of could not be used.
console.log(i, arr[i]);
}
