Using the try-catch statement Generally, we use the try-catch statement to handle errors in JavaScript. We can try to access the object or its properties in the ... Read More

The first array is the subset of the second array if the second array contains all elements of the first array. So, sometimes we may be required to check if one array is the subset of another. In this tutorial, we will learn to check if one array is a subset of another array using three different approaches. Use the for loop and array.includes() method Users can use the for loop to iterate through every element of the first array. After that, they can use the includes() method to check if the second array contains every element of the first ... Read More

In the HTML, the radio buttons allow developers to create multiple options for a choice. Users can select any option, and we can get its value and know which option users have selected from the multiple options.

Sometimes, after accessing the DOM elements, developers may require to check if both accessed elements are the same or not. In this tutorial, we will learn to use the strict equality operator of JavaScript and a method of jQuery to check the equality of two HTML elements. Using the equality operator (==) in JavaScript We can access the HTML element by getElemenetById, querySelector, getElementByClassName, etc. methods. After that, we can store it in the JavaScript variable, and we can compare those ... Read More

In JavaScript, an array is an object with an index as a key and array values as a value of a particular key of an array object. Sometimes, we require to check if two arrays are the same or not. The first solution that comes to mind is using the equality operator and comparing them like array1 == array2. Oops! It will not work as the array is an object, and we can’t compare two objects directly in JavaScript. So, we have to compare every element of the array. In this tutorial, we will learn to compare two JavaScript array ... Read More
