Learn JavaScript from Scratch JavaScript for Everyone - Array Iteration

The video tutorial explains two methods for looping over arrays in JavaScript: the traditional 'for' loop and the modern 'forEach' function. It demonstrates how to use a 'for' loop to iterate over an array, highlighting the importance of setting a condition to avoid infinite loops. The tutorial then introduces the 'forEach' function, a more modern approach that simplifies the process by using a function to iterate over array elements. The video concludes by comparing both methods, emphasizing the prevalence of 'forEach' in modern JavaScript while acknowledging the continued relevance of 'for' loops for compatibility with older browsers.
