Javascript can put dynamic content into a webpage using DOM Manipulation and get data from both frontend or backend. It empowers developers to provide a good user experience to their users.
- The main benefit of immutability is that it helps you build pure components in React.
- When you appear for a JavaScript interview, there are certain concepts that you should be thorough with to be able to pass the interview.
- Lessons and insights from building software for production.
Features of JavaScript have been extended to mobile development and game development. Plus, front-end development is in huge demand in the market. The features we teach in this course are stable and have been supported by all major browsers for several years. Go to your test site and create a new folder named scripts. Within the scripts folder, create a new text document called main.js, and save it.

If…else – learn how to execute a block of code based on a specified condition. Primitive vs. reference values – understand two value types in JavaScript, including primitive and reference values, and the differences between them. The reference contains examples for all properties, methods and events, and is continuously updated according to the latest web standards. JavaScript is the world’s most popular programming language. In this tutorial, we’ll learn by example how to build a web application and its user interface from scratch using Angular 11 and Bootstrap 4. A few years ago I was playing around with JavaScript trying to find the cleanest way to implement callbacks in functions. Primarily I wanted a readable way to make certain the last argument passed is a callback, withut having to rely on knowing how many arguments there are and so on.

Immutable data can easily determine if changes have been made, which helps to determine when a component requires re-rendering. After these changes, we’re again able to click on the Squares to fill them, the same as we had before. However, now the state is stored in the Board component instead of the individual Square components. When the Board’s state changes, the Square components re-render automatically. Keeping the state of all squares in the Board component will allow it to determine the winner in the future. Next, we need to change what happens when a Square is clicked.
