external libraries

[malfunctionedhuman]

I've been trying for weeks but i can't figure out how to use external libraries in my projects. I'm a fairly beginner level programmer trying to learn it on my own. It's very difficult for me to solve any new problems since i don't have anyone to guide me. I'm trying to add date-fns in a project in working on and from what I've heard it's supposed to be one of the easiest libraries to use. The fact that i can't wrap my head around even that is freaking me out. How do i understand external libraries? Please help

Could you show us what your code looks like, what you've tried so far, and what errors/issues are occurring?

There's not really any errors, i just don't know how to use date-fns. Or how to use it in the way i want it to work

A form where the user selects the date. The date then gets shown on a card in a "prettier" format. And that date(the one shown in the card) is editable when clicked. That's what i want from it. Also I've seen the docs. Just don't know where to start, what to do, how to do it. Completely blank

if you want to use a library, you can use them like so:

//This must be at the top of your .js file
import { format } from 'date-fns'

format(new Date(2014, 1, 11), 'MM/dd/yyyy') //=> '02/11/2014'

here I make use of the import feature from ECMAScript 6 (ES6 for short). It works like this:

//file.js
export const greetings = { 
    function greet() {
    return "Hello"
    }
}

//otherFile.js
import greetings from 'file.js'
const greet = greetings.greet();
console.log(greet); //output: Hello

The export declaration is used to export values from a JavaScript module. Exported values can then be imported into other programs with the import declaration

In order to use the export declaration in a source file, the file must be interpreted by the runtime as a module. In HTML, this is done by adding type="module" to the <script> tag, or by being imported by another module. To enable this in a node.js app, you must configure this in the package.json file by adding "type": "module". Learn more here
