Module object/map

map

• map<O, R>(fn: ObjBaseBy<O, R>, obj: O): Record<keyof O, R>
• map<K, V, R>(fn: ObjBase<K, V, R>): <O>(obj: O) => Record<keyof O, R>

• Applies fn to each of the obj values, and returns new object.

  example

   var double = x => x * 2;
  
   map(double, {x: 1, y: 2, z: 3}); //=> {x: 2, y: 4, z: 6}
  

  Type parameters

  • O: Record<any, any>

  • R

  Parameters

  • fn: ObjBaseBy<O, R>

    The function to be called on every value of the input obj. Receives three argument, value, key, obj.

  • obj: O

    The object to be iterated over.

  Returns Record<keyof O, R>

  The new object.

• Applies fn to each of the obj values, and returns new object.

  example

   var double = x => x * 2;
  
   map(double, {x: 1, y: 2, z: 3}); //=> {x: 2, y: 4, z: 6}
