Chapter 5.2: Strings

A string is also considered a collection, due to the fact it is a collection of characters.

We can perform many string operations (similar to lists) like indexing, reversing, and even joining!

obj my_string = "12345";
obj first_char = charat(my_string, 0); 

bark(first_char); # 1

String Operations

The string type actually doesn't have the ability to modify in place; i.e. it is immutable. For most string operations, you actually create a new copy that can be assigned to something.

Reversing a string is a great example, as the string is copied, then recreated in reverse.

obj forwards = "abcd";
obj backwards = reverse(forwards);

bark(backwards); # dcba

Strings support some mathematical operands too. The + operand adds two strings together, and you can even use the * operator to multiply a string.

obj hello_world = "Hello, " + "world!"; 
bark(hello_world); # 'Hello, world!'

obj excited_happy_birthday = "Happy Birthday!" * 3; 
bark(excited_happy_birthday) # 'Happy Birthday!Happy Birthday!Happy Birthday!'

Other String Operations

Similar to lists, strings come with a bunch of built-in operations other than the ones listed here. A full list of available operations is in the string documentation.
