Transforming a three-dimensional array into a two-dimensional array using JavaScript

I need help transforming a 3D array into a 2D array with specific dimensions. The current structure of my data is as follows:

[ [[0,0,345], [1,0,555], ... [9,0,333]], ... [[0,9,1000], [1,9,987], ... [9,9,129]] ]

The goal is to convert it into this format:

[[0,0,345], [1,0,355], ... [9,0,333], [0,1,1000], [1,1,987], ... [9,9,129]]

In the new format, the first element will represent the width value and the second element the height value. The third element will be a random number between 0 and 1023.

Both the width and height will have a value of 10. My aim is to eliminate the outermost array in the process.

I've attempted to iterate through each row and create a new array using push, but I'm getting unexpected results. Any assistance would be greatly appreciated!

Answer №1

To simplify the process, you can utilize the Array#flat method.

const arr = [ [[3,2,345], [8,7,555], [6,5,333]],  [[1,2,1000], [9,8,987], [5,4,129]] ];
const res = arr.flat();
console.log(JSON.stringify(res));

Answer №2

Give this flatmap a shot. Check out the example below.

let information = [[["service charge (example)"], [2000]], [["Product A...", "Product B..."], [800, 1200]], [["Product C...", "Product D..."], [500, 700]]],
    output = data.flatMap(([left, right]) => left.map((value, index) => [value, right[index]]));

console.log(output);
