External function does not support jQuery types

In my theme.js file, I currently have the following code:

jQuery(function ($) {
  accordion($)
})

const accordion = ($) => ...

By placing the accordion function directly into the jQuery function, Typescript is able to assist with the installed jquery type declarations. However, in the above markup, I do not receive type support for my accordion function.

Is there a solution to address this issue?

Additionally, I want to mention that VS Code is providing typescript support for the js file.

Answer №1

Basically, if your project doesn't utilize TypeScript within the context of const accordion = ($), the $ is considered implicit any because VSCode cannot assume it's jQuery.

You have two choices to adapt the type system to your requirements: either incorporate TypeScript into your project or use:

/**
 * @param {JQuery} $ - the jquery instance
 */
const accordion = ($) => {

};

This unique syntax is known as a jsblock, and it enables intellisense features for non-TypeScript projects.

By doing this, VSCode should recognize the type of $ and activate the intellisense.
