Value vs. Reference

Learn how arrays, objects, and functions differ from the other data types. Learn what this means when we pass them to functions and when we try to copy them.

This is an extremely important concept. It details how the behavior of objects, arrays, and functions is different from that of strings, numbers, booleans, null, and undefined.

I wrote this lesson in the second part of this course series, Step Up Your JS: A Comprehensive Guide to Intermediate JavaScript.

Some of the examples there use concepts that you might not understand; just try to get a general understanding.

See you in the next lesson.
