JavaScript Basics

Abstract

• Statements in JavaScript fall into three basic types: – Simple statements – Compound statements – Control statements • Simple statements are typically assignments, function calls, or applications of the ++ or -operators. Simple statements are always terminated with a semicolon. • Compound statements (also called blocks) are sequences of statements enclosed in curly braces. • Control statements fall into two categories: – Conditional statements that require some test be evaluated – Iterative statements that specify repetition
