Set – learn how to use the Set type that holds a collection of unique values. For…of – learn how to use the for…of loop to iterate over elements of an iterable object. Callback functions – introduce you to the callback functions and learn how to use the callbacks to handle asynchronous operations.
- In general, though, JavaScript is considered an accessible programming language to learn given its ubiquity, the many free and robust resources available online, and its ease of use.
- This lesson introduces you to the JavaScript programming language to create a foundation for the upcoming lessons.
- One reason I love @pluralsight training is how they curate similar courses on a subject into a learning path.
- Server Applications – Node JS is built on Chrome’s Javascript runtime for building fast and scalable network applications.
- It is used on both server-side and client-side to build interactive web pages, applications, and games.
- Considering tons of opportunities and features this language has to offer, every student must learn this language and Boyaa!
Primitive vs. reference values – understand two value types in JavaScript, including primitive and reference values, and the differences between them. Don’t just watch or read about someone else coding — write your own code live in our online, interactive platform. You’ll even get AI-driven recommendations on what you need to review to help keep you on track. The reference contains examples for all properties, methods and events, and is continuously updated according to the latest web standards.
JavaScript Course
JavaScript is a weakly typed language, where certain types are implicitly cast . This is a great introduction to the language filled with dozens of challenges JavaScript Lessons along the way. Beau Carnes will walk you through all of the basic freeCodeCamp JavaScript challenges and provide detailed explanations along the way.
Forums are also an opportunity to network and show off any web design skills. Some professionals get their start with an online JavaScript course or a coding boot camp. Others earn bachelor’s degrees in computer science or data science to learn foundational concepts of the field or opt for online master’s degree programs in data science. First, it’s important to become familiar with the different types of data available and how they are represented in the language.
Variables
The array reduce is a useful method in JavaScript that helps reduce an array to a single value. This lesson familiarizes you with array reduce, reducer and accumulator, properties of array reduce, and some examples that help you understand how they operate and how to use them. Array filters are used in JavaScript to filter out certain elements of an array based on the test condition specified by the programmer. To perform this, the filter goes through each element to check if it meets the test condition to filter them out accordingly. This lesson is all about array filter and how it works along with easy-to-understand examples that enable you to use them.
An event is an action that occurs based on the instructions given by the user as input to give output. You will learn about types of JavaScript and some common event listeners in this lesson with the help of code snippets. The JavaScript callback function is executed after the execution of another function is complete. It is executed in another function and is passed as an argument to that function. This lesson sheds some light on the importance and types of callback functions along with examples.
