let startDate = new Date();

Tests:

Using Math

const getNextMonth = (startDate) => {
  let current;
  if (startDate.getMonth() == 11) {
    current = new Date(startDate.getFullYear() + 1, 0, 1);
  } else {
    current = new Date(startDate.getFullYear(), startDate.getMonth() + 1, 1);
  }

  return current.getMonth();
};

let startDate = new Date();
getNextMonth(startDate);

const getNextMonth = (startDate) => {  let current;  if (startDate.getMonth() == 11) {    current = new Date(startDate.getFullYear() + 1, 0, 1);  } else {    current = new Date(startDate.getFullYear(), startDate.getMonth() + 1, 1);  }​  return current.getMonth();};​let startDate = new Date();getNextMonth(startDate);

Using Date Object

const outputDate = (date, output = 'month') => {
  switch (output) {
    default:
    case 'month':
      return date.getMonth();
    case 'fulldate':
      return date;
    case 'year':
      return date.getFullYear();
  }
};

const changeMonth = (current = new Date(), change) => {
  if (change === 0) return current;

  const unformatted = new Date(current).setMonth(current.getMonth() + change);
  const formatted = new Date(unformatted);
  return formatted;
};

const getNextMonth = (current = new Date(), output = 'month') => {
  const nextMonth = changeMonth(current, 1);
  return outputDate(nextMonth, output);
};

let startDate = new Date();
getNextMonth(startDate)

 
const outputDate = (date, output = 'month') => {  switch (output) {    default:    case 'month':      return date.getMonth();    case 'fulldate':      return date;    case 'year':      return date.getFullYear();  }};​const changeMonth = (current = new Date(), change) => {  if (change === 0) return current;​  const unformatted = new Date(current).setMonth(current.getMonth() + change);  const formatted = new Date(unformatted);  return formatted;};​const getNextMonth = (current = new Date(), output = 'month') => {  const nextMonth = changeMonth(current, 1);  return outputDate(nextMonth, output);};​let startDate = new Date();getNextMonth(startDate)

Small Date Object

const changeMonth = (current, change) => {
  if (change === 0) return current;

  const unformatted = new Date(current).setMonth(current.getMonth() + change);
  return new Date(unformatted);
};

const getNextMonth = (current) => {
  return changeMonth(current, 1).getMonth()
};

let startDate = new Date();
getNextMonth(startDate)

 
const changeMonth = (current, change) => {  if (change === 0) return current;​  const unformatted = new Date(current).setMonth(current.getMonth() + change);  return new Date(unformatted);};​const getNextMonth = (current) => {  return changeMonth(current, 1).getMonth()};​let startDate = new Date();getNextMonth(startDate)

Even smaller Date Object
const getNextMonth = (current) => { const unformatted = new Date(current).setMonth(current.getMonth() + 1) return new Date(unformatted).getMonth() }; let startDate = new Date(); getNextMonth(startDate)
const getNextMonth = (current) => {
const unformatted = new Date(current).setMonth(current.getMonth() + 1)
return new Date(unformatted).getMonth()
};

let startDate = new Date();
getNextMonth(startDate)

Autogenerated LLM Summary (model llama3.2:3b, generated 6 months ago):

Measuring the performance of different approaches to calculate the next month in JavaScript is an interesting task.

Overview

The benchmark tests four different approaches to calculate the next month:

Using Math: This approach uses the getMonth() method to get the current month, and then adds 1 to it to get the next month.
Using Date Object: This approach creates a new date object with the same date as the input date, but sets the month to the next month using the setMonth() method.
Small Date Object: This approach uses a smaller date object to achieve the same result as the previous approach.
Even Smaller Date Object: This is similar to the Small Date Object approach, but even more concise.

Options Compared

The benchmark compares the performance of these four approaches on different types of devices and browsers:

Device Platform: Desktop
Operating System: Windows

Pros and Cons of Each Approach

Using Math:
- Pros: Simple and easy to understand.
- Cons: May not be as efficient as other approaches, especially for large dates.
Using Date Object:
- Pros: More efficient than the Using Math approach, especially when dealing with large dates.
- Cons: Requires creating a new date object, which can be overhead.
Small Date Object:
- Pros: Even more efficient than the Using Date Object approach.
- Cons: May not be as easy to understand for developers who are not familiar with this syntax.
Even Smaller Date Object:
- Pros: Very concise and efficient.
- Cons: May be difficult to understand for developers who are not familiar with this syntax.

Library and Syntax Used

None of the approaches use any external libraries or JavaScript features other than what is built into the language.

Special JS Feature or Syntax

The Small Date Object approach uses a unique syntax that creates a new date object by setting the month directly. This syntax is specific to older versions of JavaScript (before ECMAScript 2015) and may not be supported in modern browsers.

Other Alternatives

If none of these approaches were considered, other alternatives could include:

Using a library like Moment.js or Luxon, which provide efficient date manipulation functions.
Implementing a custom date calculation function using bitwise operations or other low-level techniques.

However, these alternatives may not be as efficient or easy to use as the benchmarked approaches.
