Haskell LanguageData.Text


Remarks

Text is a more efficient alternative to Haskell's standard String type. String is defined as a linked list of characters in the standard Prelude, per the Haskell Report:

type String = [Char]

Text is represented as a packed array of Unicode characters. This is similar to how most other high-level languages represent strings, and gives much better time and space efficiency than the list version.

Text should be preferred over String for all production usage. A notable exception is depending on a library which has a String API, but even in that case there may be a benefit of using Text internally and converting to a String just before interfacing with the library.

All of the examples in this topic use the OverloadedStrings language extension.
