Splatting (v3) Easier to read code Separates input data from script logic Downside: No Intellisense for parameters HashTable (Parameters) HashTable (Parameters) Command Call

Where/ForEach Method Syntax Use a fluent-style syntax instead of PowerShell pipeline Filter (Where) Filter (Where) Objects ForEach

Classes (v5) Create custom object types Add properties and methods Decorate classes with existing attributes Lexical vs. dynamic scoping of variables Class Properties Methods Constructors Overloads Static Initializers Private class members are not supported Inheritance / interfaces not supported Namespaces

PSTypeNames Append custom type names to existing objects Apply a custom type to a PSCustomObject Use the [PSTypeName()] parameter attribute to constrain input objects Object PSTypeNames PSTypeName

.NET Formatting Value substitution Date formatting Numeric formatting Custom formatters Format String Objects

Variable Squeezing Simplified syntax to assign variables and print output

Type Casting Convert objects from one type to another Explicitly declare variable types Some types support “Parse” method instead Int32 Int64
