  • ¶

    Taken from Underscore, this is a predicate that identifies ownership of an attribute.

    For example:

     hasOwnProperty({}, 'foo') // => false
 hasOwnProperty(null, 'foo') // => false
 hasOwnProperty({ foo: 'bar' }, 'foo') // => true

    var has     = Object.prototype.hasOwnProperty;
var isBlank = require('./isBlank');

module.exports = function(obj, prop) {

    If the object is blank, just return false. Otherwise check for membership. This prevents errors where null or undefined are accidentally provided to hasOwnProperty

      return isBlank(obj) ? false : has.call(obj, prop);
};
