Introduction to Lua Programming


Course Number: LUA-100

Duration: 2 days (13 hours)

Format: Live, hands-on

Lua Training Overview

Lua is a free, open-source programming language that is popular as an embedded plugin/extension language in different software products, In addition, Lua can also be used as a standalone language.

Lua is both powerful and easy to use with a reputation for being high performance, extremely portable, lightweight, and embeddable.

This Lua Programming training course teaches attendees how to write middle-sized standalone Lua programs and script software products where Lua is the embedded language. Students learn fundamental programming constructs in Lua, as well as concepts that are useful in other areas of software engineering.

Headcount Cap: Due to the intensive instructor interaction in this class, headcount is capped at 10 attendees per delivery.
