Jump to navigation Jump to search

Bind () is a primitive operator. It shares the glyph Jot () with Beside; in many dialects the two operators share the name Compose. Its derived functions can only be called monadically.

Called with an array left operand A and function right operand g, (Af) X is equivalent to A f X.

Called with a function left operand f and array right operand B, (fB) X is equivalent to X f B.

Common usage

Bind is used to create a derived function with a single constant argument, particularly in tacit programming:
