Rest parameters allow functions to accept an indefinite number of arguments as an array, providing flexible and elegant solutions for variadic functions. With over 25 years of experience in software development and as the creator of CoreUI, I’ve used rest parameters extensively for building flexible utility functions and component APIs. From my expertise, the most effective approach is using the three-dot syntax ... followed by a parameter name to collect remaining arguments. This ES6 feature replaces the need for the arguments object with cleaner, more predictable code.
