How does Lua determine if two strings are equal?

In Lua, you can use the == operator to determine if two strings are equal. For example:

local str1 = "hello"
local str2 = "world"

if str1 == str2 then
  print("字符串相等")
else
  print("字符串不相等")
end

The output result is “strings are not equal” because the values of str1 and str2 are not equal.

In addition, Lua also offers functions in the string library for comparing strings, such as using the string.compare function.

local str1 = "hello"
local str2 = "world"

if string.compare(str1, str2) == 0 then
  print("字符串相等")
else
  print("字符串不相等")
end

This code also outputs “strings are not equal”.
