Why Is This JavaScript Project Awesome?

If you've ever used JavaScript frameworks like React, Vue or Angular, at some point you've probably wondered "How the $&%! does this actually work behind the scenes?"

Well in this project-based course, you'll learn exactly that by building your own Javascript framework from scratch!

You'll learn the core building blocks of a framework - state management, reactivity & declarative syntax - which will also give you a thorough understanding of why we use frameworks in the first place.

Through this project you'll build a unique skillset that will make you a better programmer. You'll understand how the frameworks you use are built which will allow you to make better decisions around which frameworks to use, and how to take advantage of their features most effectively.

And if you haven't connected the dots yet, this will of course be a skillset that is extremely impressive to showcase in interviews!

By the end you'll have an extremely unique resume project to showcase when applying for jobs which will make your portfolio truly stand out.

Wait... What's a Project?

One of the most common things we hear from students is: "I want to build more projects!"

We love hearing that, because building projects is really the best way to learn. And unique, challenging projects can really make your portfolio stand out for potential employers.

But also...it just feel so good when you actually build something real!

That's why we've created ZTM Projects. A collection of comprehensive portfolio and practice projects that you can use to advance your knowledge, learn new skills, build your portfolio, and sometimes even just have fun!

You're struggling to make progress using free tutorials that aren't giving you the structure or clear path to achieving your goals.
You don't want to learn alone. You want personalized feedback, support, and motivation from instructors and mentors and want to be part of a supportive community of like-minded individuals.
You want to learn by doing. You're excited to embrace the struggle of making mistakes that comes with building fun real-world projects you'll be proud of.
You're sick of outdated & boring tutorials. We pride ourselves on having the most up-to-date (and fun!) courses in the industry so that you're not wasting your time and only learning what matters right now.
You can't afford to spend $8,000+ on over priced bootcamps and colleges. We got you. We'll help you go from zero to hired for less than the cost of a cup of coffee a day.

We're not for you if:

You're just going to watch the lessons and take no action. Our courses are all about getting your hands dirty with exercises and putting what you're learning into action by building fun and impressive real-world projects.
You're not ready to invest in yourself or just looking for the cheapest way to learn. If that's you, no problem, use our free Learn to Code + AI & Get Hired guide.
You don't think fundamentals matter anymore because AI can do everything for you. Understanding the fundamentals and how things really work will always be important.
You think AI is going to replace you and think there's nothing you can do about it. Well... if you keep wasting time not learning AI tools & skills, you're probably right. Or you embrace them, and 2x your productivity (and probably income too!).
