🧡 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 every method.
The every() method executes a function for each array element.
The every() method returns true if the function returns true for all elements.
The every() method returns false if the function returns false for one element.
The every() method does not execute the function for empty elements.
The every() method does not change the original array
🔷 Syntax :
// Callback function
every(callbackFn)
every(callbackFn, thisArg)
// Inline callback function
every(function(element) { /* … */ })
every(function(element, index) { /* … */ })
every(function(element, index, array){ /* … */ })
every(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.
