Rendering an infinite number of unspecified arrays with JavaScript

Regarding this discussion on JavaScript string concatenation behavior with null or undefined values: Link

I have been attempting to render an array composed of an infinite number of arrays of objects, some of which may be undefined. I am seeking a more elegant approach to address this issue as my current solution lacks professionalism.

const theFunction = () => {
    let EveryArrayGoesHere = []
    try {
        EveryArrayGoesHere = EveryArrayGoesHere.concat(array1, array2, array3 ...)
        if (EveryArrayGoesHere) {
            EveryArrayGoesHere = JSON.stringify(EveryArrayGoesHere)
            EveryArrayGoesHere = EveryArrayGoesHere.replace('null,', '')
            EveryArrayGoesHere = EveryArrayGoesHere.replace(',null', '')
            return JSON.parse(EveryArrayGoesHere);
        } else {
            return 'data not available';
        }
    } catch (e) {
        if (e) {
            console.error('data error', e.message)
        }
    }
}
console.log('array of objects:',theFunction() )

Hopefully, I've accurately comprehended your inquiry.

var retriever = [];
var info = [
  [9,8,7],
  undefined,
  [6,5,4],
  [3,2],
  undefined,
  [1]  
];
// console.log('info => ', info);
info = info.filter(v => { return Array.isArray(v)}).forEach(a => { retriever = retriever.concat(a) });
console.log('retriever => ',retriever);
