6.1 Types of Statements

Conceptually speaking, there are five core types of statements:

Statements that control the execution flow of a program

loops

conditionals

ifFrameLoaded

Statements that declare variables

var

set

Statements that declare, call, and return values from functions

function

function call

return

Statements that deal with objects

with

for . . . in

Statements that represent a data value

any expression (especially expressions with side effects)

These informal categories help us understand what we can tell the interpreter to do using statements. At first glance, the list may seem fairly limited. However, we'll see that there are many variations of conditionals and loops and that there are thousands of things we can do with function calls. First, let's see how statements are formed.
