Reviews summary

Foundational javascript for beginners

According to learners, this course offers a strong foundation in JavaScript, making complex topics like variables, data types, conditionals, and loops accessible. Students particularly praise the hands-on approach, with the eCommerce shopping cart project standing out as a valuable experience for applying concepts. While it's an excellent starting point for beginners, some suggest that those with prior programming experience might find the pace slow. It effectively teaches core concepts, though further study is needed for advanced JavaScript topics, and content updates are always beneficial given JavaScript's rapid evolution.

Pacing is excellent for absolute beginners, potentially slow for others.

"As a total newbie, the pace was perfect for me to absorb all the new information thoroughly."

"If you have any prior programming experience, parts of this course might feel a bit too basic and slow-paced."

"I wished there were more challenging exercises for those who pick things up quickly."

Provides strong basics but requires further study for advanced topics.

"This is a great starting point for JavaScript, but don't expect to be an expert afterwards."

"I feel confident with the basics, but I know I'll need to take more advanced courses to truly become proficient."

"While the course covers the fundamentals thoroughly, it doesn't dive deep into more complex JS features."

The e-commerce project effectively consolidates learning into practice.

"Building the eCommerce shopping cart was a great way to apply everything I learned in a practical setting."

"The practical exercises and the final project made the concepts stick and boosted my confidence."

"I appreciated the hands-on approach; it's much better than just watching lectures without application."

Provides a solid grounding in JavaScript fundamentals for new learners.

"The explanations of variables and data types were incredibly clear, even for a complete beginner."

"I finally understood conditional statements and loops thanks to the practical examples provided."

"This course really helped me grasp the basics of functions and arrays, which felt overwhelming before."

JavaScript evolves rapidly; some concepts might need modern updates.

"I noticed a few minor practices that felt a bit outdated compared to modern JavaScript standards."

"It's a good intro, but I hope they keep the content updated with the latest ES features as JS constantly changes."

"While the core principles are timeless, some examples could benefit from newer syntax and approaches for relevancy."
