In this tutorial, we will be discussing how to design a calculator using JavaScript with a neumorphic effect, also known as a soft UI. Neumorphism is a design trend that has been growing in popularity in recent years and is characterized by its soft, rounded edges and light/dark shading. Designing the Calculator The first step in designing our calculator is to come up with a basic layout. We will be using a 12-column grid, with the following elements − A input field for the user to enter numbers A output field for the results of the calculations A series ... Read More
JavaScript is a versatile scripting language that can be used in a number of ways. One such way is to use it to get information about the current URL. This can be useful in a number of situations, such as when you want to create a bookmark or when you want to redirect the user to a specific page. Using the Location Object The easiest way to get information about the current URL is to use the Location object. This object is a property of the window object and contains information about the current URL. To use it, simply call ... Read More
In JavaScript, functions are first-class objects, which means they can be passed as arguments to other functions. This is a powerful feature that can be used to create some interesting patterns. One such pattern is the "invoke- each" pattern, where a function is created that invokes each provided function with the arguments it receives. Why Use the Invoke-Each Pattern? There are a few reasons why you might want to use the invoke-each pattern. First, it can be used as a way to abstract away the details of how a set of functions are invoked. This can be helpful if the ... Read More
Let us understand first about regular expressions before jump into I flag. A string of characters that creates a search pattern is called a regular expression. The search pattern can be applied to text replacement and search operations. A regular expression might be a simple pattern with one letter or a more complex one. Text search and replace operations of every kind can be carried out using regular expressions. The literal notation and the constructor are the two methods for creating a RegExp object. The literal notation consists of a pattern among both two slashes and optionally flags beyond ... Read More
In this tutorial, we'll be discussing how to render a list without rendering an engine in JavaScript. We'll go over the different methods and techniques that can be used to achieve this. Method 1: Using the Array.forEach() Method One way to render a list without rendering an engine in JavaScript is to use the Array.forEach() method. This method can be used to iterate over an array and execute a callback function for each element in the array. The callback function can be used to render the list. For example, we can use the callback function to create a list item ... Read More
Let us understand first about regular expressions before jumping into the /g flag. A string of characters that creates a search pattern is called a regular expression. The search pattern can be applied to text replacement and search operations. A regular expression might be a simple pattern with one letter or a more complex one. Text search and replace operations of every kind can be carried out using regular expressions. The literal notation and the constructor are the two methods for creating a RegExp object.

Iterator functions are used to iterate through arrays, lists, and other data structures. In JavaScript, there are several ways to get the index at which a value should be inserted into a sorted array. Using the Array sort() and indexOf() Methods The sort() method can be used to sort an array in ascending or descending order. The default sort order is ascending, so if you want to get the index at which a value should be inserted into a sorted array, you can use the sort() method with a compare function. After the array is sorted we could apply the ... Read More
In JavaScript, filtering an array can be done by using the filter() method. This method is used to create a new array with all the elements that pass the condition provided in the callback function. However, what if we want to filter out the values for which the comparator function does not return true? Syntax arr.filter(compare) Here compare is a comparator function used to compare the elements in the array arr. We could define it to return true or false. On the basis of the return value of the compare function, the function “filter” filters the array. Algorithm ... Read More
Protocol The URL segment that specifies the data transfer protocol to be utilised is referred to as the protocol of a URL. In this example, https:// indicates for the HTTPS protocol. We will learn how to obtain the website URL for the currently seen webpage or website in this article. The 'URL' property of the Document object, which has data on the current URL, is used to get the current URL. The "URL" property returns a string that includes the complete address of the currently seen page as well as the HTTP protocol, such as (http://). Syntax Following is the ... Read More
When a user accesses a web application using JavaScript, the "navigator" object contains details about the browser they are currently using. You may be aware that each browser functions differently when it comes to how it interprets JavaScript. In this case, the navigator object supports in modifying your application to the user's browser preferences. The browser engine or product name can be viewed in JavaScript by accessing the "navigator.product" attribute of a navigator object. In any browser, "Gecko" is always the value of the Navigator.product property. Only compatibility considerations are used to maintain this characteristic. Syntax The JavaScript syntax for ...
