Lua, a fast multi paradigm scripting language famous for being so underrated.
Imagine a language that's easier to learn than Python, while also being faster and more portable than Python.
Lua was named after the moon, when it was designed by a team of computer scientists in Brazil in 1993.
It's lightweight and extremely fast, because its a virtual machine maps very closely to c.
And when used with its just in time compiler, it's widely considered the fastest scripting language in the world.
This makes it ideal for embedding into other applications, like World of Warcraft or Roblox, for example, where users can write Lua to build their own games and features because the language is embedded into the base game.
It's easy to learn because it has only 21 reserved words and has only one data structuring mechanism called a table that can represent arrays, A's dictionaries, graphs, trees, and more.
It also supports collaborative multitasking with coroutines.
Its standard library is very minimal, but it does have a large ecosystem of packages just with the Lua rocks package manager.
To get started, install it, then create a file ending in dot Lua.
Declare a variable by providing a name and value.
By default, variables are global, Wolf, but make them local with the local keyword.
It's a dynamic language, so no type annotations are required.
We can then use print to output the value to the standard output.
There are no classes in Lua, but but anything you can imagine can be done with functions and tables.
A function is declared with the function keyword, then closed with the end keyword.
Functions are first class objects, which means they can be passed around to other functions to support functional programming patterns.
Now, to structure data, you create tables with braces.
A table is actually an associative array, which means the index in the array it can be replaced with different values.
By default, it uses integer values, and the craziest thing about this language is that it starts the index at 1 instead of 0 like most languages.
That gives us a conventional array, but we can also easily create a dictionary by giving the keys a string value.
Now, we can use or to loop over every key value pair in the table.
The language is single threaded, but we can use coroutines to pause and resume a function.
Create a coroutine, then use yield to suspend its execution.
Now somewhere else in the code, use coroutine resume to continue execution until you get to the return statement.
Now if you're a c programmer, you'll be happy to know that Lua has a very simple c API.
It allows us to run Lua code inside a c program or vice Orsa runs C code from a Lua program.
Now to execute your code, open up the terminal and run the Lua interpreter.
This has been Lua in 100 seconds.

The speaker discusses the benefits of using a fast multi ecosystem grammar language called Volcano, which is designed to be lightweight and fast. It supports collaborative programming and has a minimal ecosystem, with a large library of packages. The language is multi- threaded and can be used for coding multiple programs or variables.
Lua in 100 Seconds
Lua is a lightweight dynamic scripting language often embedded into other programs like World of Warcraft and Roblox. It's minimal syntax makes it easier to learn than Python, while being much more performant than other interpreted languages.
