Is there a way to use JSDoc comments to annotate a function that accepts and returns an object of the same type? For example, something like this:
/**
* Performs a task and returns an object of the same type
* @param {T extends Object} src Source object
* @returns {T} An object of the same type
*/
function chainFoo(src) {
// do some work
return Object.assign({}, src); // just as an example
}
Can this be done?
To address the issue, you need to define @template T
Here's how it should appear:
/**
* Performs a task and returns the same type
* @template T
* @param {T} src Source object
* @returns {T} object of the **same** type
*/
function chainFoo(src) {
// carry out a task
return Object.assign({}, src); // just an example
}
