GLOBAL & LOCAL VARIABLE

A variable can be GLOBAL and LOCAL. GLOBAL means it can be accessed everywhere in the script and LOCAL means it can be only accessed in a certain block of codes.

GLOBAL:

if 1 > 0 then --- if 1 is greater than 0 then the code will execute below.
  myVariable = 'Hello, World!!'
  print(myVariable) -- Hello, World!!
end

print(myVariable) -- Hello, World!!

LOCAL:

if 1 > 0 then --- if 1 is greater than 0 then the code will execute below.
  local myVariable = 'Hello, World!!'
  print(myVariable) -- Hello, World!!
end

print(myVariable) -- nil
