I’m trying to combine 3 arrays into one "2d array":
resultArr = [
["abc", 0, []],
["def", 0, []],
["ghi", 0, []],
["jkl", 0, []],
["mno", 0, []],
["pqr", 0, []],
["stu", 0, []]
];
Basically, I’m starting with an arbitrary array as my input, such as snippets
:
Array 1:
const snippets = ['abc', "def", "ghi", "jkl", "mno", "pqr", "stu"];
The next steps was easy, I created a an array filled with zeros:
Array 2:
const zeros = new Array(snippets.length).fill(0); // [0, 0, 0, 0, 0, 0, 0]
Now, I tried the same to get a list of empty arrays:
Array 3:
const zeroArr = new Array(snippets.length).fill([]); // → circular object arrays :(
Obviously, fill cannot handle nested arrays .fill([])
or .fill([[]])
. Is there any way to create this nested array structure?
FYI: I continue to combine these rows like so, it works if I would leave out the last , zeroArr[0][i]]
part:
let combined = [];
for (let i = 0; i < genreLength; i++) {
combined.push([snippets[i], zeros[i], zeroArr[0][i]]);
}
