Hi,
can someone help me with implementing the function prefixer? I'm a bit lost.
'use strict'
const sayHiTo = prefixer('Hello ')
const sayByeTo = prefixer('Goodbye ')
function prefixer (str) {
console.log(str);
}
console.log(sayHiTo('Dave')) // prints 'Hello Dave'
console.log(sayHiTo('Annie')) // prints 'Hello Annie'
console.log(sayByeTo('Dave')) // prints 'Goodbye Dave'
Thx a lot

- Return a function from prefixer that accepts an argument
- concat (e.g. use
+) the outstrargument and the returned functions argument together

The sayHiTo and sayByeTo functions expect a string argument called name. So the prefixer function should return a function that takes a name. As prefixer has it's own argument (greeting) in the outer scope you can use it in the scope of the returned function. Closures are common and confusing

Prefixer function definetion for quick refence could be =
pass an argument "greeting", -> return an child fuction -> pass an argument "name" -> concate both argument "greeting+''+name" and return.
