## 3.12 String

Strings are enclosed in double quotes ("), but is not a data type in Erlang. Instead, a string "hello" is shorthand for the list [$h,$e,$l,$l,\$o], that is, [104,101,108,108,111].

Two adjacent string literals are concatenated into one. This is done in the compilation, thus, does not incur any runtime overhead.

Example:

"string" "42"

is equivalent to

"string42"
