JavaScript's forEach() is a simple method to loop through arrays. It enhances code readability but doesn't support break, continue, or async operations.

Learn how JavaScript's throw statement handles errors, enhances debugging, and improves code reliability.

JavaScript's map() efficiently creates new arrays by applying a callback to each element, useful for data transformation without modifying the original array.

JavaScript's filter() method creates a new array with elements passing a test. It’s great for data filtering, with best practices for performance and clarity.

JavaScript's find() and findIndex() help locate elements in arrays. find() returns the element, while findIndex() returns its index.
