Groupby array of unique values with lodash

Question

I have an array of ids, I want to have an array of arrays each containing their unique values, for example if I have an array like this:

const arrayOfIds = [1,2,2,4,2,4,5,5];

I want to get a resulting array like the following:

[
    [1],
    [2,2,2],
    [4,4],
    [5,5]
]

Thanks in advance

You can do something like this

 const arrayOfIds = [ 1,2,2,4,2,4,5,5 ]; const output = Object.values(_.groupBy(arrayOfIds)); console.log(output);
