1 2 3const object = { a: 1, b: 2, c: 3 }; const keys = _.keys(object); console.log(keys); // Output: ["a", "b", "c"]
In this example, the _.keys function is used to extract the keys of an object and store them in an array. The resulting array contains the keys "a", "b", and "c", which correspond to the properties of the original object.
