I'm relatively new to computer programming. I have no long background--I've only started learning early in 2020. I'm currently a student in a bootcamp for Javascript and needed some extra help and guidance so I can stay on pace with my curriculum.
When I first posted my questions on Codementor, he was one of the first to respond and one of the first to actually review my questions and files I uploaded. He quickly offered me a Zoom session, where he was incredibly helpful.
I took a second lesson with him and it's clear he knows the language very well. But it's not enough for someone to just know the language very well. They must also be personable. Olawale is very personable, affable, and makes you feel comfortable as a student. He is good at breaking down aspects of JS so I can understand them clearly before utilizing them with more intricacy.
I would recommend him as a teacher to anyone who is looking for help in learning JS. I haven't had a reason to ask him about other computer programming languages, but I know that he knows other ones as well.
