I am working on web scrapping and I came across one scenario where I am get confused about arrow key function,I am unable to understand why url is used twice and how it is actual working, I know it is advanced javascript but I need some explanation to understand this completely.

first Url in arrow function:

const fethHtml = async url => {

Second url pass in axios.get

await axios.get(url);

const fethHtml = async url => {

const axios = require("axios").default; const fethHtml = async url => { try { const { data } = await axios.get(url); return data; } catch { console.error( `ERROR: An error occurred while trying to fetch the URL: ${url}` ); } };

My question is what url is indicating here is it variable or function and why it is called twice, I didn't found any explanation anywhere.

    Variables are not called. They're created and referenced. Commented Jan 10, 2022 at 9:11

    async url => { creates a variable to be used inside the fetchHtmlz function, whereas axios.get(url)` passes that variable into the axios.get function. This is not unusual. Commented Jan 10, 2022 at 9:14

const fethHtml = async url => {

url is just arguments. (ex:google.com)

then pass the arguments to axios to get resposne.

await axios.get(url);
