shape

Transforms one or several Spots into a new value. Works inside run.context, enabled.context, and createWire.from.

• shape<S, T>(spot, fn) — Returns a Spot<T>. fn receives the value of spot
• shape<S, T>(sources, fn) — Returns a Spot<T> from a record or array of Spots. fn receives an object or array of their values

shape(user.result, (u) => u.name.toUpperCase())

shape({ first: firstName.result, last: lastName.result }, (v) => `${v.first} ${v.last}`)

shape([firstName.result, lastName.result], ([first, last]) => `${first} ${last}`)

When shape fails, the downstream Task skips — the source Task fails, or the callback throws
