Module object/pathSetBy

pathSetBy

• pathSetBy<K, O, R>(path: [K], fn: ObjBase<K, O[K], R>, obj: O): ReplaceType<O, K, R>
• pathSetBy<K, V, R>(path: [K], fn: ObjBase<K, V, R>): <O>(obj: O) => ReplaceType<O, K, R>
• pathSetBy<K>(path: [K]): { <O, R>(fn: ObjBase<K, O[K], R>, obj: O): ReplaceType<O, K, R>; <V, R>(fn: ObjBase<K, V, R>): <O>(obj: O) => ReplaceType<O, K, R> }
• pathSetBy<O>(path: Paths, fn: ObjBase<Paths, any, any>, obj: O): O
• pathSetBy(path: Paths, fn: ObjBase<Paths, any, any>): <O>(obj: O) => O
• pathSetBy(path: Paths): { <O>(fn: ObjBase<Paths, any, any>, obj: O): O; (fn: ObjBase<Paths, any, any>): <O>(obj: O) => O }

• Returns the result of "setting" the portion of the given data structure focused by the given paths to the result of fn call.

  Note: If property in the object is equal to value by reference then function just returns object without changes

  example

   pathSetBy(['a', 'b'], x => x+1, {a: { b:1 }}) //=> { a: { b: 2 } }
  

  Type parameters

  • K: string | number | symbol

  • R

  Parameters

  • path: [K]

  • fn: ObjBase<K, O[K], R>

  • obj: O

  Returns ReplaceType<O, K, R>
