🧡 Hello All JavaScript Lovers Outhere!

Today you're going to learn about the Array Object In JavaScript.

This tutorial is a series of videos, in each video we will discuss a method (or more) of the Array Object in JavaScript.

In today's video, you're going to learn about the forEach method.

The forEach() method calls a function once for each element in an array.
The forEach() method is not executed for empty elements.

🔷 Syntax :
// Callback function
forEach(callbackFn)
forEach(callbackFn, thisArg)

// Inline callback function
forEach(function(element) { /* … */ })
forEach(function(element, index) { /* … */ })
forEach(function(element, index, array){ /* … */ })
forEach(function(element, index, array) { /* … */ }, thisArg)

🔹callbackFn : Function to execute on each element.
The function is called with the following arguments:

🔹element : The current element being processed in the array.
🔹index : The index of element in the array.
🔹array : The array forEach() was called upon.
🔹thisArg (Optional) : Value to use as this when executing callbackFn.

Sorry, am asking to many questions... why is the name of the function u are using called function log(){}.... I thought log() is a predefined function for the console.... it confusing if it's a function declaration like this function log(){}

the THIS keyword always refer to an object that is invoking the function or method in a TRADITIONAL Why are u using the ARROW FUNCTION HERE? I know that the ARROW function is short with implicit return... but it doesn't always point to the Object invoking it....Pls Are u making video to explain the use of arrow function in an event, loop or nested function?
