The Instructor is patient, his explanation is wonderful and clear and the content is great and 100% applicable to my job.

By Leonardo on 4/28/2022

Laurence has the power to summarize better than other experts. Syntentize and offer exactly what we need to be developers. He has absolute control of time, between 6-8 minutes his workflows let us a better learning curve. I will continue with another Laurence lecture. Thanks a lot, Laurence.

By David Aste on 2/28/2022

This is a very complex subject as is, the Q&A section is extremely lacking and there is no support from the teacher of the course. I will update my review once my questions have been answered to prove that this is an up-to-date course actually worth the money. As of now, I recommend a newer version.

By Theresa A. Haaser on 11/14/2021

Exactly the way a course should be taught. It is straightforward and engaging. The code solutions after each core video is a plus!

By Marco Alvarado on 11/20/2020

The basic knowledge of APIs+JS+JSON is quite well discussed. Little excersises help to deepen the understanding. CORS should be mentioned at the beginning of the course.

By James Gillis on 6/18/2020

Learning about one of the most important parts of the web. Some of the links needed for exercises do not work.

By Janet Nevins on 5/17/2020

Another GREAT course!! This course is a very detailed course. The instructor is very knowledgeable and a great teacher.

By Leopoldo Vargas Gonzalez on 12/19/2019

It is well explained and with many examples, I like when Laurence has to debug the unintentional errors, since this is something that could happen to anyone. Including Google sheets and scripts in the script was really awesome! It would be great to include more advanced troubleshooting while working with APIs, such as CORS.
