Yep, nailed it, @shilpa.chandel. Having spent time maintaining both modern and legacy codebases, I’d add that with ES6 giving us the spread operator, the javascript apply vs.call
debate has softened a bit. You can now do everything apply
did using call
with spread syntax, like func.call(thisArg, ...argsArray)
.
So today, developers tend to lean toward call
because it reads more cleanly and aligns better with modern syntax practices. But apply
still has its place — especially in legacy code or when you’re unsure whether all environments support spread. In real-world use, I mostly pick the one that fits the data structure I’m working with. At this point, it’s really about readability and intent more than performance.
