What is a common use case for bind in JavaScript?
Passing a method as a callback while preserving this. For example, setTimeout(obj.method.bind(obj), 1000) ensures the method runs with this as obj, not the global object.

More FAQs in How this Changes With call, apply, and bind in JavaScript
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.
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.
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.
