What is the main difference between arrow functions and regular functions in JavaScript?
Arrow functions have lexical this (inherited from the enclosing scope), no own arguments object, cannot be used as constructors (no new), and no prototype. Regular functions have call-time this, own arguments, can be constructors, and have a prototype.

No. Arrow functions cannot be used as constructors. Calling new ArrowFn() throws TypeError: ArrowFn is not a constructor. They do not have a [[Construct]] internal method or a prototype property.
No. Arrow functions do not have their own arguments object. If you reference arguments inside an arrow, it refers to the enclosing regular function's arguments. Use rest parameters (...args) in arrows instead.
No. Arrow functions inherit this from their lexical scope at definition time. call, apply, and bind can still pass arguments but cannot change the arrow's this.
