Here are some short points about Lua, for those who already know other computer programming languages and how to program. They focus mainly upon what you might find different in Lua. Lua is dynamically typed. There's no static typing at all.
Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...
Step debugging is a powerful tool that allows you to step through code one line at a time, and hover over variables to see their contents at the time of execution. IDEs that easily support Lua step debugging include ZeroBrane Studio , and IntelliJ IDEA with various debugger plugins ( Emmy Lua or Lunalysis ).

A project of Google, it is free and open-source software released under the Apache License 2.0. [2] It typically runs in a web browser, and visually resembles the language Scratch. Blockly uses visual blocks that link together to make writing code easier, and can generate code in JavaScript, Lua, Dart, Python, or PHP.

The debugger supports the following functions: step through the code, set/remove breakpoints, inspect variables and expressions using the Watch window, inspect the call stack with local values and upvalues (local values defined in the outer scope of the current function) using the Stack window, suspend/resume the running application, and run ...
