External module "utils/property-names-in/docs/types/index.d"

Export assignment propertyNamesIn

• propertyNamesIn(value: any): Array<string>

• Returns an array of an object's own and inherited enumerable and non-enumerable property names.

  Notes

  • Name order is not guaranteed, as object key enumeration is not specified according to the ECMAScript specification. In practice, however, most engines use insertion order to sort an object's keys, thus allowing for deterministic extraction.
  • If provided null or undefined, the function returns an empty array.

  Parameters

  • value: any

    input object

  Returns Array < string >

  a list of own and inherited property names

  Example

  var obj = {
      'beep': 'boop',
      'foo': 3.14
  };
  
  var keys = propertyNamesIn( obj );
  // e.g., returns [ 'beep', 'foo', ... ]
