Future course updates (5 years)This course covers the TypeScript concepts you need when working with web applications. It builds on top of your existing JavaScript knowledge with a unique approach: explaining concepts step by step so you can fully understand how TypeScript works.
The lessons & challenges will guide you through these topics step by step:
TypeScript concepts in isolation can be easy to understand. However, when mixed together, it becomes challenging to identify them. That's why the course includes many Mix-n-match challenges where you combine previously learned concepts with new ones.
Apply everything you've learned by building a Book Library app from scratch using TypeScript. The project covers typed DOM interactions, classes, interfaces, generics, and more.
A dedicated video lesson covering how to use TypeScript with React, so you can confidently apply your TypeScript knowledge in the most popular frontend framework.
Through this course, Jad has helped me build the mental models and the foundation that I needed to better understand TypeScript. I can now eliminate those pesky squiggly lines one at a time, while leveraging its powerful type-checking features.
This course helps me a lot to organise myself and a nice structure of learning TS is already created for me. I just need to follow the route and do my best to understand. Moreover, it's really easy to understand because Jad provided us with good explanations and immediate practice of learned material.
Here are some of the most asked questions. If you have any other question, consider
You need to be intermediate in JavaScript. You should be familiar with most of the concepts in the JavaScript knowledge map. In general, you should be able to work with arrays, objects, classes, functions, promises, and the DOM.
You need basic HTML and CSS experience. As long as you can perform some basic DOM operations in JavaScript, that should be enough.
Yes, it is a one-time payment that gives you access for 5 years.
If you'd like to use the app after those 5 years, you will have to make a new payment. We will not automatically charge your card and there is no automatic renewal.
We believe that you should not have to pay monthly except for Gas, Water & Electricity (and maybe Netflix). This encourages you to take your time while working on the course, rather than rushing it. Note that the payment is only valid for this course.
The majority of students will not need to access their accounts past the 5 years mark. After 5 years, your account will be downgraded from PRO. You will have the option to upgrade again. There is no automatic renewal and your card will not be automatically charged.
Yes, you can! You can pay in your own currency so that you don't incur a cost for currency exchange. Contact support if your currency is not available in the dropdown above (subject to availability).
