Strings

• Quotes:
  • Single quotes '...': Literal, does not parse variables or escape sequences
  • Double quotes "...": Interpolated string, parses variables and ` escape sequences
• Concatenation: Use + or interpolation
• Multi-line strings (Here-String): @"..."@ or @'...'@

Example:

$name = 'Alice'
"Hello, $name"
'Path: C:\\Temp'  # Single quotes don't need to escape backslashes
@"
Line1
Line2 $name  # Supports interpolation
"@

Formatting:

'{0} scored {1:P2}' -f 'Alice', 0.8765

$Matches.prefix  # abc
$Matches.num     # 123
'foo bar' -replace '\s', '_'  # foo_bar
