What you will learn

  • Separate display text from structured values and streams.
  • Choose explicit edition, input, output, and file-format assumptions.

  1. Choose an edition and discover command contracts

    Separate PowerShell 7, Windows PowerShell 5.1, command resolution, help, platform support, and actual execution evidence.

  2. Preserve objects through the pipeline

    Inspect object members, filter and project properties, and postpone display formatting until structured work is complete.

  3. Define types, nulls, and collection contracts

    Distinguish scalar values, arrays, hashtables, objects, conversion, and comparison behavior before relying on a convenient display.

  4. Read syntax, quoting, and control flow explicitly

    Separate expression and argument parsing, expandable strings, script blocks, conditions, loops, and status boundaries.

    Start learning

  5. Design functions with precise output contracts

    Declare parameters, validate inputs, manage scope, and keep incidental success output from corrupting a reusable functionโ€™s result.

  6. Separate providers, paths, bytes, and serialized data

    Explain provider-specific operations, literal paths, content modes, encoding differences, and JSON/CSV contracts without touching host files.
