CodeFast vs. CodeKidz vs. JavaScript vs. Next U Comparison Chart

CodeFast is a coding course that claims to take users from zero experience to launching a working SaaS or online business in a matter of weeks. The curriculum includes about 12 hours of video tutorials that cover everything from basic web fundamentals (HTML, CSS, JavaScript) to full-stack development (frontend with frameworks like Next.js/React and styling with Tailwind CSS, backend logic, database management, API routes, user authentication, and database operations), as well as business-oriented topics like payment integration (e.g. subscriptions via Stripe or similar), domain setup, deployment, and hosting. It emphasizes a “learn-by-doing” and practical approach, rather than deep theory, guiding learners to build real projects from day one, which helps many beginners overcome the inertia of “tutorial hell.” Many students reportedly complete the course and launch simple web apps or micro-SaaS products within weeks.

JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.
