I tried to do this
string.len("hi") and strin = "hi" print(#strin)
They both printed two but what I wanted to clarify is if they're exactly the same or a bit different because some thing that are same or similar tend to be a bit different you know what I mean hozei!!
Hello, xxcoordinatorxx!
string.len(string) and print(#string) don't really have a big difference, the only one that I can remember is that # can be used to Tables. I'll give some examples...
local string = "A text"
print(string.len(string)) -- This will print '6'
print(#string) -- This will print '6'
however,
local string = {"Nice", "Explanation", "Leamir", 12348, true}
print(string.len(string)) -- This will print nil, as "string" is now not a string, but a table
print(#string) -- This will print 5, as the table "string" have 5 indexes
It is better use # for strings and tables, as it works for both
Any errors please post a comment and I'll solve
Good Luck with your games
No, you should use # on strings.
Uhh... Normally you use .length or :len() on strings. However, # is a little more powerful as it gets the length of strings and tables.

they are essentially the same but you can check the length of a table with #
Will the # (operator) also return nil as a result or not ? In a table of course!!!
nope
Use #. len probably is there because there wasn't a proper length operator, but idk
I was curious myself so I tested them both in a speed test, string.len() is significantly less efficient so I would use #string instead
