Tunisian crochet, each row is a two-step process, and you never have a need to turn the work.
The first part of the process, called the "forward," is similar in some ways to casting on in knitting. When working this part of the row, you draw up a series of loops, which are all held on the hook until you complete the second part.
The second part, called the "return," has similarities to the technique of binding off in knitting.
