In JavaScript, there are multiple ways to extract a number from a string. One way is to use the match() method and a regular expression to search for all numeric digits in the string. Another way is to use the replace() method and a regular expression to remove all nonnumeric characters from the string, leaving only the numbers. Let’s understand each of the methods with the help of some examples. Using the match() method and regular expression The regular expression is one kind of search pattern which we can create by combining multiple alphabetic and special characters. We can ... Read More

AJAX stands for Asynchronous JavaScript and XML. It is a set of web development techniques to create interactive web applications. AJAX allows a web page to communicate with a server without reloading the page. Ready states are an important part of working with AJAX requests. The ready state of a request indicates the request’s status to the server and allows the client to track the progress of the request. In the below, we detailed the different ready states of AJAX. UNSENT STATE (0) This is the first ready state of the AJAX. It is denoted by the integer 0. When ... Read More

In JavaScript, timers are a very noteworthy feature. As like the normal watch timer, we can start the timer at a time and execute the function or code in JavaScript after a particular time. In simple terms, we can use the timer to execute the code after some delay. For example, when you visit some website, it shows the signup box after 3 to 4 minutes of your visit, and that we can achieve using JavaScript. We can set the delay timer to show the signup popup box. Another good example of the timer in real life is ads ... Read More

In JavaScript, we have different ways to define the functions. The function foo() {} and var foo = function() { } is two different ways to define the function. Both ways have their benefits and different use cases; however, both give the same result when executing the function. So, this tutorial will teach us the difference between both ways to define a function. Explanation of the function foo() { }: function declaration The function foo() { } is the normal way to declare the function in JavaScript, which every beginner and developer uses.

In the ES6 version of JavaScript, spread syntax is introduced as a very powerful feature. We can use the spread syntax to expand the array or objects into the variable of the same data type. For example, before the spread syntax was introduced in the ES6, developers were using the for loop to copy all elements of one array to another array. Can you copy all elements of one array to another by writing one linear code using the spread syntax rather than writing the 5 to 7 lines of code using the for loop? Yes, you heard right! ...

As the web storage word represents, it stores the data inside the user’s browser locally. Before HTML 5, developers were using cookies to store data locally, but the cookies allow for storing a limited amount of data, such as in kilobytes. The local storage allows users to store up to 5 MB of data. Developers use the cookies to store the data in the browser and exchange it between the client and server. When we store the data in the cookies, it expires after a particular time. However, we can set the data's expiry, but it still expires after ... Read More

In JavaScript, the scope defines how and in which part of our code we can access the variables and functions. In simple terms, the scope helps us improve our code's security and readability. So, we can access the variables and functions only inside its scope but not outside. We will discuss multiple types of scopes in this tutorial. Global Scope in JavaScript The variables and functions defined globally mean outside all blocks and functions with global scope. We can access all variables and functions with the global scope anywhere inside our code. Syntax Users can follow the syntax below ... Read More

JSON, or JavaScript Object Notation, is a simple format for exchanging data. It is a human−readable and machine−understandable format. It is based on a portion of Standard ECMA−262, Third Edition, December 1999's JavaScript Programming Language. Despite using conventions recognizable to programmers of the C family of languages (C, C++, Java, JavaScript, Perl, Python, and many others), JSON is a text format fully independent of the programming language. JSON is the best language for exchanging data due to its characteristics and simplicity. AJAX is a method of web development used to build interactive web applications. Web pages can request data from ... Read More
