# Expressions

• produce a value

# Statements

• perform an action
• e.g. if and loop statements
• end with semicolons

# General

• Expressions can be written wherever statements can be written. They are expression statements

var x = 5; // expression statement
x = 5 // expression

• but you cannot write statements where an expression is expected. if statements cannot be used as arguments in a function
• Anything that can be used as a value is an expression
