  • Wild Code School
    Trainer
    EDUCATION AND E-LEARNING
    February 2023 - May 2023 (3 months)
    Paris, France
    At Wild Code School, I had the opportunity to teach JavaScript and React.
    This school emphasizes the 'do before learn' principle, encouraging students to dive directly into code before delving into theory, which perfectly aligned with my teaching approach.
    Some initially struggled with this method, but I was impressed by their ability to adapt and persevere.
    Through practical projects and a hands-on approach, I saw my students overcome obstacles and make significant progress in their understanding of React.
    It was a rewarding experience to see each of them grow and succeed, even when facing initial challenges.
