The Difference Between Regular Functions and Arrow Functions in JavaScript

Other then the syntactical differences. The main difference is the way the this keyword behaves? In an arrow function, the this keyword remains the same throughout the life-cycle of the function and is always bound to the value of this in the closest non-arrow parent function. Arrow functions can never be constructor functions so they can never be invoked with the new keyword. And they can never have duplicate named parameters like a regular function not using strict mode.

Here are a few code examples to show you some of the differences
this.name = "Bob";

const person = {
name: “Jon”,

<span style="color: #008000">// Regular function</span>
func1: <span style="color: #0000ff">function</span> () {
    console.log(<span style="color: #0000ff">this</span>);
},

<span style="color: #008000">// Arrow function</span>
func2: () =&gt; {
    console.log(<span style="color: #0000ff">this</span>);
}

}

person.func1(); // Call the Regular function
// Output: {name:“Jon”, func1:[Function: func1], func2:[Function: func2]}

person.func2(); // Call the Arrow function
// Output: {name:“Bob”}

The new keyword with an arrow function
const person = (name) => console.log("Your name is " + name);
const bob = new person("Bob");
// Uncaught TypeError: person is not a constructor

Custom JavaScript Functions

Table of contents


In JavaScript you can create functions to write reusable blocks of code with functionality similar to most other programming languages, although, because of the nature of JavaScript, they might behave a bit differently, depending on the circumstances and the way you declare them.

Function declaration

In its simplest form a custom JavaScript function is declared as follows.

function myFunction() {

}

You can then call (use) this function later in your code with:

myFunction();

Now as it is, our function doesn’t actually do anything. So let’s add some functionality and delve into the subject of arguments and parameters.

Arguments and parameters

function myFunction(number1, number2) {
    console.log(number1 + number2);
}

The functionality we’ve added here is simply logging to the console the result of number1 + number2. As you can see these variables aren’t declared or defined anywhere else but between the function parenthesis. This is what are called parameters.

Parameters are variables entered as a part of the function definition. And these are the types of values we expect to be inserted when our function is called, like so:

myFunction(1,2);

The numbers 1 and 2 are passed into the parenthesis of the function when it is called, and are called arguments .

Function Expression vs Function Declaration in JavaScript

Function Expression vs Function Declaration in JavaScript.

It was until during one of the JavaScript mock interviews did I came across the term function expression.

The question was: What is the difference between these two syntax?

function x(){

}

let x = function(){

}

I was clueless for a moment. After thinking a little, I could only come up with: the second syntax invokes an _anonymous _function and is assigned to a variable.

I was alien to the term hoisting.

In this article, we will acquaint ourselves with three simple terms: function declaration,_ function expression, _and hoisting.

What is function declaration?

Function declaration is also known as _function statement. _It contains the name of the function, parameters, and a return statement. **Naming the function **is what sets function declaration apart. Parameters and return statement is optional.

Function Declaration

What is function expression?

Function expression also has a name, parameters, and return statement. All of which are optional. The important thing to bear in mind is: the function here is _assigned _to a JavaScript variable.
