The “What does this code do?” tool is your aid in unraveling the mysteries of any piece of code that puzzles you. It leverages the formidable GPT-4 (Generative Pre-trained Transformer 4) algorithm, empowering users to simply paste their code into the editor and hit the “Explain Code” button. GPT-4 will then weave a coherent paragraph to demystify the code’s purpose.

Illustrating this process, consider an example within the text: the code defines two arrays and identifies their common values, presenting the result as a set.

This invaluable tool takes the form of a Visual Studio Code (vscode) extension and encompasses a library of meticulously generated explanations. Its creator, @thebuilderjr, enjoys the sponsorship of beam analytics.

While the tool’s capabilities are impressive, they are tethered to the capacities of GPT-4, which can occasionally exhibit limitations. Thus, users should exercise discernment when assessing the tool’s explanations, verifying the results align with their expectations.

In essence, “What does this code do?” stands as a trusty companion for those confronting enigmatic code snippets. It expedites comprehension and complements existing tools and techniques, bolstering code implementation’s correctness.
