lua string length

To find the length of a string in Lua, you can use the built-in string.len() function. Here are the steps to determine the length of a string in Lua:

1. First, you need to assign the string you want to measure the length of to a variable. Let's say the string is "Hello, Lua!".

2. Next, you can use the string.len() function to get the length of the string. The function takes the string as an argument and returns the length as an integer. In this case, you would write string.len("Hello, Lua!").

3. The string.len() function will return the length of the string, which in this case is 12.

That's it! By following these steps, you can determine the length of a string in Lua using the string.len() function.
