In this article, we'll dive into the array functions introduced in ES5 and…

.includes() The .includes() method is a built-in function in JavaScript that allows you to check if an array contains a specific element. It returns a boolean value (true or false) based on whether the element is found in the array or not. Here's the basic syntax of the .includes() method:…

.push() The .push() method is a built-in function in JavaScript that allows you to add one or more elements to the end of an array. It's a simple and efficient way to append new items to the existing array. Here's the basic syntax of the .push() method: array.push(element1, element2, ...);…

.find() Certainly! The .find() method is a built-in function in JavaScript that allows you to search for the first element in an array that satisfies a given condition. It's particularly useful when you want to find a single element in an array based on certain criteria. Here's the basic syntax…

.concat() The .concat() method is a built-in function in JavaScript that allows you to combine multiple arrays into a single new array. It does so by creating a new array that contains all the elements from the arrays you pass as arguments to the method. The original arrays remain unchanged.…

.filter() The .filter() method is another useful function provided by JavaScript arrays. It allows you to create a new array containing only the elements that meet a certain condition defined by a filtering function. This method is especially handy when you want to extract specific items from an array based…

.map() The .map() method is another powerful built-in function provided by JavaScript arrays. It allows you to create a new array by applying a transformation function to each element of an existing array. This method is extremely useful when you want to transform the contents of an array while maintaining…

.forEach() The .forEach() method is a built-in function available on arrays in JavaScript. It is used for iterating over each element in an array and performing a specified action or function on each element.
