- Variables give a label for data
- Variables can be referenced in other expressions
- Variables are assigned with "const", "let", or "var"
- var is discouraged (obsolete?)
- The label can be re-pointed to new data if you use "let"
const myName = "Ryan"; let myAge = 28; const isATeacher = true; const nothing = null; var isObsolete = true; // Try to avoid this one
