This Building Web Applications with TypeScript, Angular, and React course packed with the right balance of theory and hands-on activities to help you take your TypeScript skills to the next level.

In this course, you will begin by learning the fundamentals of TypeScript and eventually move toward advanced concepts. Learn how TypeScript relates to JavaScript that you may have written before. We will understand the benefits of TypeScript and how it can help you avoid software defects. We will learn to use type guards, check null and undefined, create tagged union types, and compare the performance of algorithms.

We will use TypeScript to build a weather forecast widget with Angular. We will then progress by building a note-taking client/server application using Angular, Node.js, and MongoDB. Finally, we will create a real-time chat application with React.

This course complies with instructional designing principles for all the 4 lessons. This will ensure that you frequently repeat and reinforce the knowledge you gain. Having been designed for the development of large applications, TypeScript is being widely incorporated into popular projects such as Angular.

TypeScript is the future of JavaScript. TypeScript offers a sliding scale of how much or how little effort you want to put into your declarations: the more effort you put in, the more type safety and code intelligence you get. TypeScript allows developers to write readable and maintainable web applications. Adopting TypeScript results in more robust software, while still being deployable in apps where regular JavaScript is running.

Pure JavaScript lacks certain language features that are taken for granted in languages such as C# and Java. For example, it has no built-in module system, meaning that there’s no standard way of producing self-contained blocks of code that present well-defined interfaces to developers.
