How to check if a key exists in an object with Lodash and JavaScript?

To check if a key exists in an object with Lodash and JavaScript, we can use the has method.

For instance, we write:

const obj = {
  foo: 1,
  bar: 2
}
console.log(_.has(obj, 'foo'))
console.log(_.has(obj, 'baz'))

We call has with the obj we want to check if the key exists in and the key we’re searching for.

Therefore, the first console log logs true and the 2nd one logs false.

Conclusion

To check if a key exists in an object with Lodash and JavaScript, we can use the has method.
