Module object/mergeWith

mergeWith

• mergeWith<T1, T2, R>(fn: MergeFunc<T1, T2, R>, a: T1, b: T2): Record<keyof T1 | keyof T2, R>
• mergeWith<T1, R>(fn: MergeFunc<T1, any, R>, a: T1): <T2>(b: T2) => Record<keyof T1 | keyof T2, R>
• mergeWith<R>(fn: MergeFunc<any, any, R>): { <T1, T2>(a: T1, b: T2): Record<keyof T1 | keyof T2, R>; <T1>(a: T1): <T2>(b: T2) => Record<keyof T1 | keyof T2, R>; <T>(...args: T[]): Record<keyof T, R> }
• mergeWith<T, R>(fn: MergeFunc<any, any, R>, ...args: T[]): Record<keyof T, R>

• Create a new object with the own properties of the first object merged with the own properties of the others objects. If a key exists in several objects provided fn will be called and should return resolve value

  example

   mergeWith((x, y) => x + y, { 'name': 'fred', 'age': 10 }, { 'age': 40 }); //=> { 'name': 'fred', 'age': 50 }
