Reviews summary

Practical javascript data manipulation & asynchronicity

According to students, this course offers a solid foundation in data manipulation in JavaScript, particularly excelling in its coverage of asynchronous functions and the JavaScript event loop, which learners found incredibly clear and practical. The hands-on projects and practical examples are frequently praised for solidifying understanding and providing useful application. While it provides effective coverage of validation techniques, some learners noted that the jQuery validation aspects felt a bit dated. A few students found the pace a bit rushed for deeper topics like the event loop, suggesting it's best for those comfortable with JS fundamentals.

Offers practical projects and examples that reinforce learning effectively.

"The hands-on projects, especially the seat reservation system, really solidified my learning."

"The practical examples were very helpful and the challenge projects were perfectly designed to reinforce the concepts."

"The project pulling data from an external source was a good practical exercise; I now feel much more confident."

Provides exceptionally clear explanations of complex async JavaScript.

"The asynchronous functions and event loop explanations were incredibly clear and practical, a game-changer for my understanding."

"Explanations of arrow functions and the event loop were spot on. I learned so much about handling user input."

"Asynchronous JavaScript was presented clearly, making it easy to grasp even complex concepts."

Some feel the jQuery validation sections are less relevant for modern development.

"The jQuery validation plugin felt a bit dated, given modern JS frameworks, but it's understandable for foundational knowledge."

"The jQuery part felt a bit outdated for what I needed, although it was useful for specific front-end forms."

"While the jQuery validation was helpful for specific scenarios, I primarily needed modern JS practices, which were sometimes less emphasized."

May require existing JavaScript fundamentals; some topics can feel rushed.

"I struggled with this course... explanations were sometimes confusing, assuming too much prior knowledge."

"Not ideal for someone who isn't already quite comfortable with JS fundamentals; I had to spend a lot of time outside the course."

"Some parts felt a bit rushed, especially the deeper dives into the event loop, needing external resources to fully grasp."
