Loop through properties in JavaScript object with Lodash

Is it possible to loop through the properties in a JavaScript object? For instance, I have a JavaScript object defined as this:

myObject.options = {
  property1: 'value 1',
  property2: 'value 2'
};

Properties will get dynamically added to this object. Is there a way for me to just loop through and do a check if a property exists? If so, how?

Solution

  • Yes you can and lodash is not needed... i.e.

    for (var key in myObject.options) {
  // check also if property is not inherited from prototype
  if (myObject.options.hasOwnProperty(key)) { 
    var value = myObject.options[key];
  }
}
