Usage

var isInList = require('is-in-list');
 
var listOfAwesomePeople = [
  { name: 'Sabrina' },
  { name: 'Gustav' },
  { name: 'Mattias' },
];
 
console.log('is Sabrina awesome?', isInList(listOfAwesomePeople, { name: 'Sabrina' }));

  'limit',
  'fields',
  'pagination',
];
 
var query = {
  foo: 'bar',
  baz: 'qnx',
  sort: '-foo',
};
 
var acceptedParams = Object
.keys(query)
.filter(not(isInList(paramsBlackList)));
 
console.log('accepted param keys are:', acceptedParams);

Reasoning

Why use this and not underscore / lodash / ramda / <insert functional library here>

Because what I'm looking for is simpler than what any of those libraries have to offer. Please think of this library as a simple experiment of re-inventing the wheel to see how it works :)
