我是平台的新手，也是新的编程。 我正在学习回调，我有这个练习，我无法理解如何处理它

Question

you must create a function called callback that receives as a parameter a number and a function . this function must return the result of that function giving as an argument the parameter number

Examples..

// - callback(5, (num)=>{return num*10}) should return 50 // - callback(25, (num)=>{return num/5}) should return 5

Thanks!

Answer 1

This question is asking you to create a function, like:

const todo = () => {}

that executes a callback using the parameter to the function as the parameter to the callback, an example being:

const todo = (a, b) => {
   // call method b using a as parameter
}
