How can one create parameter information in JavaScript?

Is it possible to automatically generate parameter information in JSDoc style based on function implementation?

/**
 * Assigns the project to a list of employees.
 * @param {Object[]} employees - The employees responsible for the project.
 * @param {string} employees[].name - The employee's name.
 * @param {string} employees[].department - The employee's department.
 */

For example, in Microsoft Visual Studio you can simply type /// above a function and it will create XML comments for you automatically.

  /// <summary>
  /// 
  /// </summary>
  /// <param name="input1"></param>
  /// <param name="input2"></param>
  /// <returns></returns>
  public static decimal Add(string input1, string input2)

Answer №1

While there are editor plugins such as docthis available for Visual Studio Code that can assist with writing out parameter types in JavaScript, it may not be as precise as what you would get for C#. However, this same extension can also be used for TypeScript files, providing more accurate definitions. As a C# developer, transitioning to TypeScript could be an enjoyable experience.

(NOTE: If you prefer the editor to automatically generate parameter types for you, VS Code has built-in support for creating boilerplate by typing /** and pressing Tab. Other editors likely offer similar functionality through plugins.)

Answer №2

When using the editor, typing backslash(/) followed by two stars(**) and then pressing enter or return will create function information.

However, it is important to first define the function with parameters.

If you need help documenting JavaScript, JSDOC can be a useful tool. It is compatible with both IntelliJ and Visual Studio. Additionally, for Visual Studio Code users, there is a plugin available here.

For those using Sublime Text, the package DocBlockr can be quite helpful.
