Answer:

• Variables are containers for storing information.
• Creating a variable in JavaScript is called "declaring" a variable: var carName.
• In JavaScript, variables are declared using the 'var' keyword, followed by the variable name and an optional initial value.
• After the declaration, the variable is empty (it has no value).
