Module object/propApply

propApply

• propApply<K, R, O>(prop: K, fn: ObjBase<K, O[K], R>, obj: O): R
• propApply<K, V, R>(prop: K, fn: ObjBase<K, V, R>, obj: any): R
• propApply<K, V, R>(prop: K, fn: ObjBase<K, V, R>): (obj: any) => R
• propApply<K>(prop: K): { <V, R>(fn: ObjBase<K, V, R>, obj: any): R; <V, R>(fn: ObjBase<K, V, R>): (obj: any) => R }

• Returns the result of fn with value of property in obj.

  example

   propApply('a', x => 'is ' + x, {a: 2}); //=> is 2
   propApply('b', x => x > 0, {b: 2}); //=> true
