lodash groupBy

Comment

Creates an object composed of keys generated from the results of running 
each element of collection thru iteratee. The order of grouped values is 
determined by the order they occur in collection. The corresponding value 
of each key is an array of elements responsible for generating the key. 
The iteratee is invoked with one argument: (value).

_.groupBy([6.1, 4.2, 6.3], Math.floor);
// => { '4': [4.2], '6': [6.1, 6.3] }
 
// The `_.property` iteratee shorthand.
_.groupBy(['one', 'two', 'three'], 'length');
// => { '3': ['one', 'two'], '5': ['three'] }

export const groupArrayBy = (arr, groupBy) => {

    let newArr = []
    arr.map((item) => {
        if(item[groupBy]) {
            let finded = newArr.filter((newItem) => newItem[groupBy] === item[groupBy])
            if(finded.length > 0) {
                finded[0].products.push(item)
            } else {
