Module object/all

all

• all<K, V>(fn: ObjPred<K, V>, obj: Record<K, V>): boolean
• all<K, V>(fn: ObjPred<K, V>): (obj: Record<K, V>) => boolean

• Tests whether every [key, value] pair in the object passes the test implemented by the provided function.

  example

   var isBiggerThanZero = x => x > 0;
  
   all(isBiggerThanZero, {}); //=> true
   all(isBiggerThanZero, { a: 1 }); //=> true
   all(isBiggerThanZero, { a: 1, b: 1, c: 1 }); //=> true
   all(isBiggerThanZero, { a: 0, b: 1, c: 0 }); //=> false
   all(isBiggerThanZero, { a: 1, b: 0, c: 1 }); //=> false
   all(isBiggerThanZero)({ a: 0, b: 0, c: 0 }); //=> false
   all(isBiggerThanZero)({ a: 1, b: 0, c: 1 }); //=> false
  

  Type parameters

  • K: string

  • V

  Parameters

  • fn: ObjPred<K, V>

    The function to test for each [key, value] pair. Takes a predicate and an object.

  • obj: Record<K, V>

    The object whose enumerable own property [key, value] pairs are to be tested.

  Returns boolean

  Returns true if the callback function returns a truthy value for every [key, value] pair, otherwise, false.

• Tests whether every [key, value] pair in the object passes the test implemented by the provided function.

  example

   var isBiggerThanZero = x => x > 0;
  
   all(isBiggerThanZero, {}); //=> true
   all(isBiggerThanZero, { a: 1 }); //=> true
   all(isBiggerThanZero, { a: 1, b: 1, c: 1 }); //=> true
   all(isBiggerThanZero, { a: 0, b: 1, c: 0 }); //=> false
   all(isBiggerThanZero, { a: 1, b: 0, c: 1 }); //=> false
   all(isBiggerThanZero)({ a: 0, b: 0, c: 0 }); //=> false
   all(isBiggerThanZero)({ a: 1, b: 0, c: 1 }); //=> false
