Pattern: Use of Array#forEach

Issue: -

Description

Using for...of loops instead of Array#forEach() provides better performance, readability, and control flow (ability to use break or return). It also enables better type-narrowing in TypeScript without crossing function boundaries.

Examples

Example of incorrect code:

const foo = [1, 2, 3];
foo.forEach((element) => {
  /* ... */
});

Example of correct code:

const foo = [1, 2, 3];
for (const element of foo) {
  /* ... */
}
