In the ROBLOX Lua environment, _G is a predefined global table that contains all the global variables, functions, and other values that are accessible throughout the game. You can use _G to access and manipulate these global values, as well as to define new global values.
However, you should not be using _G due to the issues of race conditions, Roblox loading order when it comes to scripts is undefined. Since _G exists on the VM stack the same way a module would, it would be much better to use a module as you can add extra functionality into the module to control when it loads _G.
_G is a global variable (not a function) that holds the global environment, that is, _G. _G = _G . Lua itself does not use this variable; changing its value does not affect any environment, nor vice-versa. Use setfenv() to change environments.
Shared provides the exact same purpose of _G. There is no difference. Just that they’re in different scopes.
Deprecated implies that it will be removed. _G is a language global and still present in old projects. I don’t imagine it’s far-fetched to call it legacy but it won’t get deprecated.
Is Roblox _g replicated?
_G is a module script like any other. It is unique to each client and the server, setting _G. my_value = true will not be replicated to clients or the server.
Does Roblox allow C++?
Does Roblox use C++? Yes, Roblox does also use C++ as well as Lua. When kids code with Roblox, they will be using Lua in the Roblox Studio, but some of the software used for memory management in the background has been developed with C++.
Is _G slow?
_G IS NOT SLOWER THAN MODULESCRIPTS.
It makes no difference if you use _G or require(modulescript) both do the exact same thing and both are as fast.

What are Roblox pairs?
pairs() can be used to work with a dictionary element’s key, value, or both. In the for loop below, the first variable is the key. The second variable is the value. The dictionary that you want to work with is passed in to pairs().
What is the _g in code?
_G is a global variable that holds the global environment. BugSack (and many other addons) are usually setting a local reference to that environment using “local _G = getfenv(0)” in the beginning of the code.
What does == mean in Lua?
The operator == tests for equality; the operator ~= is the negation of equality. We can apply both operators to any two values. If the values have different types, Lua considers them different values. Otherwise, Lua compares them according to their types. Specifically, nil is equal only to itself.
What is the difference between _ENV and _G in Lua?
_ENV is not a global, but an upvalue or a local variable. The _G field of the default “global environment” points back to the global environment. _G and _ENV by default refer to the same table (said global environment).
