flatten to extract errors from object - lodash

Question

How do I convert a list like this into flattened array of error messages:
"errors": {
"Client": [
"User client does not exist"
],
"Password": [
"User password has to have more than 6 characters",
"The password and confirmation password do not match."
],
"ConfirmPassword": [
"Confirm Password has to have more than 6 characters"
]
},
tried var arr = _.toArray(data.errors); but it doesnt flattent the objects that have multiple items in the array.

Lodash
Use _.values() (or _.toArray()) to get an array of error message arrays, and _.flatten() to convert to a single array.
const errors = {"Client":["User client does not exist"],"Password":["User password has to have more than 6 characters","The password and confirmation password do not match."],"ConfirmPassword":["Confirm Password has to have more than 6 characters"]}
const result = _.flatten(_.values(errors))
console.log(result)

Vanilla JS
Use Object.values() to get an array of error message arrays, and Array.flat() to convert to a single array
const errors = {"Client":["User client does not exist"],"Password":["User password has to have more than 6 characters","The password and confirmation password do not match."],"ConfirmPassword":["Confirm Password has to have more than 6 characters"]}
const result = Object.values(errors).flat()
console.log(result)
