tostring() is a function that converts (almost) any given data type to a string. There are numerous uses for it:
- Converting something to a string to perform formatting on it.
- Converting a number, or almost any other data type, to a string for concatenation purposes. In Roblox only, you are able to concatenate a number to a string without using
tostring(). However, you needtostring()for any other data type. - Converting a boolean to a string for printing purposes, or GUI purposes.
- etc.
For conditional purposes, tostring() will viably compare its given data type to a string. Two examples of this:
print(tostring(10) == "10") -- true
print(tostring(5 * 6 > 4^2) == tostring(true)) -- true
When converting tables to strings, it will just give the identifier instead of the table contents:
print(tostring({})) -- table: <identifier>
For concatenating numbers, tostring() is not necessary. This print, for example...
print(5 .. 6) -- 56
...will convert both numbers to strings before concatenating them.
tostring is a function that converts a given number to a string. This can be useful for stuff like if statements. If you want to compare say, a math equation to a TextBox's text, you will need to use tostring (or tonumber) to compare the two, as two different data types can not be compared.

it does not have to be number, it converts any given value to string: Instances, tables, etc.
