singularDimension.js

var pancake = function pancake(inputArray) {
  return inputArray.reduce(function (accumulation, value) {

    if(Array.isArray(value)) {
      return accumulation.concat(pancake(value));
    } else {
      return accumulation.concat(value);
    }
    
  }, []);
};

var testArray = [[1,2,[3]],4];
console.log(pancake(testArray));
