1. [Variables: \`$name\`](https://www.ask-codey.com/lessons/powershell-variables) (Apprentice): A variable is a name PowerShell keeps a value under, so $owl = "…" stores a long path once, $drawings = Get-ChildItem … keeps a whole list of files, and $owl hands the value back in any later command until you close the window.
2. [Text: Quotes and \`$( )\`](https://www.ask-codey.com/lessons/powershell-strings) (Apprentice): Double quotes fill in the values of variables and single quotes keep text exactly as typed, $( ) puts a property or a whole command's answer into text, and a here-string holds text of many lines.
3. [Numbers, Dates and Types](https://www.ask-codey.com/lessons/powershell-types) (Apprentice): Every value in PowerShell has a type, such as a whole number, text or a date; \[int\], \[decimal\] and \[datetime\] turn text into the type you need, and subtracting dates, AddDays and Get-Date -Format answer questions such as how many days are left until a trip.
4. [Lists and Lookups: Arrays and Hashtables](https://www.ask-codey.com/lessons/powershell-arrays-and-hashtables) (Journeyman): An array keeps several values in order, made with commas or @( ) and read by position from \[0\], and a hashtable, made with @{ }, keeps values under names so you can look one up by its name, the way you'd find a word in a dictionary.
