What is partial application with bind in JavaScript?
Presetting some arguments of a function using bind. const add5 = add.bind(null, 5) creates a new function where the first argument is always 5. When called with (3, 2), it calls add(5, 3, 2).

call and apply invoke the function immediately with a specific this (call takes comma-separated args, apply takes an array). bind returns a new function with this permanently bound, to be called later.
Use call or apply. For example, Array.prototype.slice.call(arguments) borrows the slice method to convert the array-like arguments object into a real array.
No. Arrow functions inherit this from their lexical scope at definition time. call, apply, and bind cannot change an arrow's this. They can still pass arguments, but this stays the same.
