Gatsby is presented as an effective tool for learning JavaScript, React, Node.js, and GraphQL by providing a high-level framework that allows learners to focus on advanced concepts without getting bogged down by basic technical details. The author argues that starting with abstractions rather than core technologies accelerates learning, similar to tasting a cake before baking one. Gatsby's CLI and Gatsby Cloud facilitate project creation and content management, enabling users to quickly build and experiment with React-based projects. The availability of numerous Gatsby plugins and themes further enhances the learning experience by offering ready-made functionalities that can be integrated into projects. The author highlights personal experiences and suggests that engaging with Gatsby's ecosystem provides transferable skills across various web development frameworks, advocating for its use in educational initiatives like #100DaysOfGatsby to progressively build expertise.
