Getting started with Lua (Part 3)

Basic Programming Constructs — Level 2 (conditional statements)

Note : Click here for Part 1 and Part 2

In this piece we will cover the simplest programming construct; a conditional statement and also get introduced to some core concepts in Lua.

1. if-else condition

2. if -else if-else conditional blocks

if-else

The basic syntax for if-else and if-else conditional blocks are as shown below

if-else conditional construct

if-else if — else

An extended if-else block is where you can specify multiple conditional statements in your code block as shown below

Each piece of code in lua is called a chunk. It just a name to refer to a sequence of statements of code. Nothing more.

It could be an entire program in a code , a function or just a few lines of code. Its just a naming.
