Javascript – How to Return an Array from a Nested ForEach Method?

I have been working with a data structure for days and days, and am finally getting the data I want from it using a nested forEach loop. Trouble is, I’m getting a string for each loop, so in my console. I see a long list of individual strings for each item. I need to see an array of all of the strings.

Can anyone tell me how I can change my code to achieve this result? Or am I going about it the whole wrong way? Thanks.

  data.forEach(brandGuideline => {
    brandGuideline.children.forEach(child => {
      const brandGuidelineAlias = child.component.alias;
      console.log(brandGuidelineAlias); // Long list of individual strings. Can this be an array? 
    });
  });

I have tried creating an empty array and pushing my data into it, but that didn’t work because I was inside of the forEach — so I ended up getting a huge array for each of the items. Duh.

I have also tried wrapping my logic in a function and pushing the data into an array at the end, but that doesn’t work because the array is out of scope. Blah.

Here is what I had tried earlier (in answer to Barmar):

let arrayOfAliases = [];
  data.forEach(brandGuideline => {
  brandGuideline.children.forEach(child => {
  const brandGuidelineAliases = child.component.alias;
  console.log(brandGuidelineAliases); // Need to only show buttons if 
  'brand-guidelines' is part of the path.
  arrayOfAliases.push(brandGuidelineAliases);
  console.log('Alias Array: ', arrayOfAliases);
  });
});
