Strings⚓︎

Strings are an important part of programming and are used in many high-level programming languages. A string is a combination of alphabetical letters, numbers, and other symbols.

Declaring String⚓︎

Strings can be declared in numerous ways however the most commonly used are by using double quotes(") and single quotes(').

local str = "EdenRose"
local user = 'EdenRose#1968'

Multi-line String⚓︎

A Multi-line string can be declared by using double brackets ([[)

local str = [[Helpers are very skilled
They help a lot in development channels.]]

local str2 = [[Helpers are the best.
They spend their free time helping out others. :) ]]

Concatenation⚓︎

Concatenation is as method by using which we can combine two strings, for doing so we use ".." between both the strings.

local str1 = "I am "
local str2 = "EdenRose"
print(str1..str2)

I am EdenRose

String Escaping⚓︎

In a string declared with (") or ('), You can produce almost any character using (\). It can be used in many ways such as having quotes inside a string without disturbing it, printing in a new line, etc.

print("Greetings \"Devs\"")
print("First line \nSecond line)

Greetings "Devs"
First line
Second line

Arithmetic With Strings⚓︎

When using arithmetic operators between strings, Lua tends to convert the string into a number.

print("7" + "22")
print("17" - 4)

29
13

Conversion⚓︎

A string can be converted into a number by simply using tonumber(), a global function of Lua.

print(tonumber("78")) 
print(tonumber("hola"))

78
nil

Similarly, a number can also be converted into a string by the function tostring()

print(tostring(78))

78
