Async and Await in JavaScript are powerful keywords used to handle asynchronous operations with promises. Async functions implicitly return promises, while Await pauses the execution until the promise is resolved. This simplifies asynchronous code and enhances readability by making it appear synchronous....
In this article, we will study in detail what exactly are Anonymous Functions in JavaScript and how to declare them using normal technique and/or with the Arrow Function technique itself....
forEach() is an array function Node that is used to iterate over items in a given array....
The explode() function is an inbuilt function in PHP used to split a string into different strings. The explode() function splits a string based on a string delimiter, i.e. it splits the string wherever the delimiter character occurs. This function returns an array containing the strings formed by splitting the original string....
Here a promise is a returned object from an asynchronous function, and callback methods can be added based on the previous function’s result. It is done for back-to-back execution of functions acting like a queue or chain of functions. So as the functions are in the queue, the functions following it must wait for the previous function’s result....
In this article, we will see how to get the length of the string using strlen() function in PHP, along with understanding its implementation through the examples....
Javascript removeEventListener() is an inbuilt function that is used to remove an event handler that was previously added using the addEventListener() function from the element....
In JavaScript, Functions within another function are called “Nested function.” These nested functions have access to the variables and parameters of the outer (enclosing) function, creating a scope hierarchy. A function can have one or more inner functions....
A JavaScript function is a block of code designed to perform a particular task. It encapsulates a set of instructions that can be reused throughout a program. Functions can take parameters, execute statements, and return values, enabling code organization, modularity, and reusability in JavaScript programming....
In native JavaScript, before ES6 Modules 2015 was introduced had no import, include, or require functionalities. Before that, we can load a JavaScript file into another JavaScript file using a script tag inside the DOM that script will be downloaded and executed immediately. Now after the invention of ES6 modules, there are so many different approaches to solve this problem have been developed and discussed below. ES6 Modules: ECMAScript (ES6) modules have been supported in Node.js since v8.5. In this module, we define exported functions in one file and import them in another example....
In this article, we will see how Node JS and React JS are an important part of developing full-stack web applications, where React is used for the front end and Node for the back end....
