Passing by reference vs. by value - JavaScript Tutorial

Показать описание

In this video I'll be demonstrating the difference between passing by "reference" vs. passing by "value" in JavaScript.

To sum it up, arrays and objects are passed by reference whereas everything else is passed by value, and passing by value makes a copy of your data.

"A single instance to the array or the object." That's the important bit that makes this so much easier to understand👍🏿

Thank you so much. It's one of the hardest concepts to explain in JavaScript but you did explain it the best way possible.

Thank you so much. This was the simplest video/ explanation out there.

Great explanation, a cool fact that functions only receive values, never reference. Although inside the function the argument can receive the object and point as well to it, as it was a object. But as rule, variables can receive both reference and value and function only can receive values.

functions are objects in js, so that means functions are passed by reference in js, right?
