I'm dealing with a large array of objects and I need to retrieve the ones that have the property def defined, regardless of its value. Any help would be greatly appreciated.

To determine if a property exists, you can utilize the hasOwnProperty method and then apply Array.prototype.filter to extract specific items.
objArray = [ { def: 1, bar: 2}, { foo: 3, bar: 4}, { def: 5, bar: 6} ];
var result = objArray.filter(item => item.hasOwnProperty('def'));
console.log(result);For compatibility with ES5:
objArray = [{
def: 1,
bar: 2
}, {
foo: 3,
bar: 4
}, {
def: 5,
bar: 6
}];
var result = objArray.filter(function(item) {
return item.hasOwnProperty('def')
});
console.log(result);Although lodash does not have a built-in function for this specific task, you can achieve the desired result by using the following code snippet:
`let filteredArray = [];
_.forEach(inputArray, function(element){
if(!_.isEmpty(element.definition)){
filteredArray.push(element);
}
};
