In [[computer science]], a '''promise''' (also known as a '''future''' in some languages) is a proxy for a result that is not yet known, usually because the computation of its value has not yet completed. They were introduced in [[1977]] in the paper by [[Henry Baker (computer scientist)|Henry Baker]] and [[Carl Hewitt]].
