let duplicates = ['Hello', 'Hi', 'hello'];
let uniques = _.methodName(duplicates);

// output should be
['hello','Hi'] OR ['Hello','Hi']

Answer 1

You can use _.uniqWith() with a callback as following:

let duplicates = ['Hello', 'Hi', 'hello'];

let uniques = _.uniqWith(duplicates, (a,b) => a.toLowerCase() === b.toLowerCase())

console.log(uniques);
