How to write your short $(function () {}) implementation for window.onload?

Question

JavaScript

There is a task for JS - Write your own short implementation $(function () {}) for window.onload.
Please explain, do I need to write the implementation of window.onload in JQuery?
What does the '$' sign in front of a function mean? Is this a jQuery function notation?

Thank you!

Answer 1

Please explain, do I need to write the implementation of window.onload in JQuery?

Are you seriously suggesting that we guess what is written in your assignment?

What does the '$' sign in front of a function mean? Is this a jQuery function notation?

No. This is a reference to a jQuery object. Synonym, if you will.

Answer 2

$(function () {})so they write in Jquery
window.onloadso they write in pure js
They do the same thing - they execute the code inside after the page has loaded.
Most likely you have a task - to write an analogue of this algorithm.
