... in JavaScript – the Three Dots Operator in JS

The three dots operator in JavaScript is one of the significant updates that was shipped with ES6. It helps you achieve many things that previously required many lines of code, unfamiliar syntax, and more. We will go through some examples to show possible use cases. We can also concatenate objects similarly to how we did arrays with the spread operator. The rest operator allows you to combine any number of arguments into an array and then do whatever you like. It uses an array to represent an infinite number of options. It is a good representation.
