ndarray.js

function NdArray(...args) { // n-1 args are dimensions, last argument is the fill value
	if(args.length === 2) {
  	return new Array(args[0]).fill(args[1]);
  }
  let arr = [];
  let newArgs = args.slice(1);
  for(let i = 0; i < args[0]; i++) {
  	arr.push(NdArray(...newArgs));
  }
  return arr;
}

let twoD = NdArray(3, 2, 5);
console.log(twoD); // Array [ Array[2], Array[2], Array[2] ]
console.log(twoD[0]); // Array [ 5, 5 ]
console.log(twoD[1]); // Array [ 5, 5 ]
console.log(twoD[2]); // Array [ 5, 5 ]
