Logs the name of a function.
|
|
|
|
- Use `console.debug()` and the `name` property of the passed function to log the function's name to the `debug` channel of the console.
|
|
- Return the given function `fn`.
|
|
|
|
```js
|
|
const functionName = fn => (console.debug(fn.name), fn);
|
|
```
|
|
|
|
```js
|
|
let m = functionName(Math.max)(5, 6);
|
|
// max (logged in debug channel of console)
|
|
// m = 6
|
|
```
