Regular VS Arrow Functions

Syntax

The arrow function allows to accomplish the same result with fewer lines of code and approximately half the typing. Curly brackets aren't required if only one expression is present.

Arguments binding

Arrow functions do not have an arguments binding. But the same functionality can be achieved using rest parameters.

const myFunction = (...args) => {
  console.log(args);
};
myFunction(1, 2, 3); // Output: [1, 2, 3]

Use of this keyword

Unlike regular functions, arrow functions do not have their own this. The value of this inside an arrow function remains the same throughout the lifecycle of the function and is always bound to the value of this in the closest non-arrow parent function.

Using new keyword

Regular functions created using function declarations or expressions are constructible and callable. Since regular functions are constructible, they can be called using the new keyword. However, the arrow functions are only callable and not constructible, so arrow functions can never be used as constructor functions. Hence, they can never be invoked with the new keyword.

No duplicate named parameters

Arrow functions can never have duplicate named parameters, whether in strict or non-strict mode.
