JavaScript Spread Syntax Explained

Hello everyone, today I’ll briefly explain what JavaScript spread syntax is and where can we use them. It’s going to be a fairly shorter one since there isn’t much to cover around the topic but I do believe that the spread syntax is now essential for everyone who writes JavaScript no matter how often they do that. You can find the examples that are about to be shared here.

What is spread?

“Spread allows an iterable such as an array expression or string to be expanded in places where zero or more arguments (for function calls) or elements (for array literals) are expected.” is the definition from the MDN Web Docs. Everything is cool but where can we actually use it, maybe we should show that on the examples.
