  1. Node.js and the JavaScript foundations

    Understand what runs a server-side JavaScript program, choose a supported release deliberately, and use values and functions without depending on browser APIs.

    Start learning

  2. Modules, packages, and npm

    Build explicit module boundaries and understand package metadata and repeatable dependency installation before adding third-party code.

    Start learning

  3. Promises and the event loop

    Reason about completion, sequencing, and cancellation without assuming that asynchronous code executes in parallel.

    Start learning

  4. Files, paths, and JSON

    Read and write small data files safely while distinguishing bytes, text, paths, and validated application data.

    Start learning

  5. HTTP requests and responses

    Use core HTTP to identify requests, send complete responses, and test a server without leaving it running.

    Start learning

  6. Configuration and command-line programs

    Turn text settings into validated configuration and make a small CLI predictable for people, automation, and tests.
