Guru99 has established itself as a reliable free learning resource, particularly for beginners entering the tech field. The site excels at breaking down complex programming concepts into digestible tutorials with practical examples. Their coverage spans from basic programming languages like Python and Java to database management and testing frameworks. The step-by-step approach with screenshots makes following along straightforward. However, some content can feel dated, and advanced developers may find the material too surface-level. The ad-heavy interface can be distracting, but considering the wealth of free educational content available, it's a reasonable trade-off. Ideal for self-learners starting their coding journey or professionals brushing up on fundamentals.
