Using lodash to check whether an array has duplicate values

Question

What do you all think would be the best (best can be interpreted as most readable or most performant, your choice) way to write a function using the lodash utilities in orde

Answer 1

Well, there's always. lodash's _.uniq() function. That function actually returns a new array that only contains unique values, so checking to see if the length of the array has changed would get you your 'true' or 'false' value to return yourself, I believe.
