The Full Show
summary
Shows concrete techniques and measurable outcomes: uses splatting, PSDDefaultParameterValues, dynamic parameters and parameter-set names to auto-generate routes, and update-typeData to add an OlderThan method and a GetValueOrDefault helper for hashtables. Benchmarks show file class wins full-file reads, while switch/streamreader wins single-line search and Get-Content is slow. For collections .Where/.ForEach outperform legacy Where-Object; a math max scan often beats sort/MeasureObject for large arrays. Schema validation is more informative but slower: JSON schema returns all validation errors.
