Array.concat()

[Casmat]

Hey!

How do I use the concat() function?

const var tagArray = [["Pad"], ["Chord", "String"], ["Pluck"]]

Trying to make ^this^ turn into this:

["Pad", "Chord", "String", "Pluck"]

Thanks!

@Casmat Array concat is used for combining two arrays, so that won't do what you want.

You need to flatten the array. I don't think there is a clean way to do it in HISE (with JS we'd usually use the spread or apply commands). So here is a dirty way using a recursive function.

const var tagArray = [["Pad"], ["Chord", "String"], ["Pluck"]]

function flattenArray(arr)
{
	var result = [];

	for (i = 0; i < arr.length; i++)
	{
    	    if (Array.isArray(arr[i]))
    	    {
      		var flattenedSubArray = flattenArray(arr[i]);
      	
      		for (j = 0; j < flattenedSubArray.length; j++)
        		result.push(flattenedSubArray[j]);
    	    }
    	    else
    	    {
      		result.push(arr[i]);
	    }
	}
	
	return result;
}

const newArray = flattenArray(tagArray);
Console.print(trace(newArray));

You might be able to get it a bit neater using the map function but I haven't explored it for this purpose.

@d-healey ahh, makes sense! Thanks!

@Casmat you can do like this

const var tagArray = [["Pad"], ["Chord", "String"], ["Pluck"]];

const result = [];

for (i = 0; i < tagArray.length; i++)
	result.concat(tagArray[i]);

Console.print(trace(result));

Interface: [
  "Pad",
  "Chord",
  "String",
  "Pluck"
]

@ulrik Oh that puts my over-engineered method to shame :D
