What Is TypeScript?

TypeScript is a programming language superset of JavaScript developed and open-sourced by Microsoft.

It adds a comprehensive type system to JavaScript which enables IDE code completion, greater program reliability, makes code easier to read and work with, and scales to large development teams.

Why Should I Learn TypeScript?

Every JavaScript Developer should learn TypeScript, as it's useful for all jobs or roles where you'd normally use JavaScript.

Importantly there's no need to re-write entire projects in TypeScript because it was designed for gradual implementation. This makes it's possible to implement TypeScript code into existing JavaScript projects over time in order to enhance maintainability and reliability.

Here's what this TypeScript Bootcamp covers:

1. TYPESCRIPT INTRODUCTION - Welcome to the course! You're going to start by going over how the course is structured, plus strategies and pro-tips to get the most out of the course. You'll also learn how to get your development environment set up and TypeScript installed, so that you'll be geared up with a fully configured development environment and ready to deep dive into TypeScript.

2. TYPESCRIPT FUNDAMENTALS - We'll lay the groundwork with basic programming concepts such as variables, functions, control flows and data structuring. You'll begin to grasp the awesome power of TypeScript by learning how to use type annotations, how to create objects, and how to work with arrays like a pro.

3. INTERMEDIATE TYPESCRIPT: BEYOND THE BASICS - Here is where the fun begins. You'll learn to master TypeScript classes, interfaces, maps, unions, and more. And the cherry on top? You'll dive into asynchronous coding and the art of unit testing.

4. TYPESCRIPT PROJECT: WEATHER APP - Time to really get your hands dirty! You'll construct a sophisticated app to fetch weather insights using the techniques and skills you've learned.

This project will also teach you about HTML templates, API data structuring, understanding HTTP dynamics, and the magic of TypeScript type definitions.

5. TYPESCRIPT UNION TYPES - Time to learn one of TypeScript's most powerful features: union types. These can be used to define all the possibilities that may occur in various situations, allowing the TypeScript compiler to check all code that uses a union type and making it super easy to update the code later (there will be a compiler error when a mistake is made!)

6. TYPESCRIPT INTERFACES - Interfaces aren't just blueprints...they breathe life into objects and functions! Interfaces act as a form of self-documenting code, which makes your codebase significantly easier to work with And the best part? TypeScript ensures they harness interfaces to their full potential.

Instead of having to read through out-of-date documentation it becomes possible to instead look at the interface and have all the information needed at your fingertips. As a bonus, TypeScript will be checking to make sure the interface is used correctly.

7. TYPE DEFINITION FILES - You'll learn how to integrate existing JavaScript projects with TypeScript easily! That's because type definition files allow existing JavaScript code to interoperate with TypeScript code.

Writing these takes some practice, so you'll be doing lots of that. But once you master type definition files they open up the entire JavaScript ecosystem to TypeScript...which is pretty great considering there are over a million packages on the npm registry!

8. TYPESCRIPT TECHNIQUES AND PATTERNS - You'll take deep dive into important TypeScript techniques and patterns, from discriminated unions to const assertions, and generics to iterators.

9. USER AUTHENTICATION - You'll develop a sleek, and surprisingly complex, user account creation and sign-in application. This project will help your practice and synthesize the knowledge you've learned from the entire course, integrating TypeScript on the frontend and backend. Plus you'll learn about database integration and effective code sharing across platforms.

Most importantly this course, like all Zero To Mastery courses, is a living thing that will be constantly updated. That means it will be your go-to place to find the latest TypeScript best practices and resources throughout your career.

What's the bottom line?

This course is not about making you just code along without understanding the principles so that when you are done with the course you don’t know what to do other than watch another tutorial. No!

This course will push you and challenge you to go from an absolute beginner to someone that is in the top 10% of TypeScript developers 💪.

And you have nothing to lose. You can start learning right now and if this course isn't everything you expected, we'll refund you 100% within 30 days. No hassles and no questions asked.

What you'll build

The best way you learn is by doing. Not just watching endless tutorials. That's why a key part of this course is the real-world projects that you'll get to build. Plus they'll look great on your portfolio.

Weather App

Weather App

Build a weather app that fetches data from an external API and uses it to display weather information using a command line interface (CLI) application that is then modified to host a web interface where users can enter their location.

User Authentication Form

User Authentication Form

A surprisingly complex application for users to create accounts and login to a website. The backend utilizes an SQLite database, OOP, HTML templates, and hashes passwords. The frontend provides live feedback as users enter their information + more.
