do we have to require fetch code example

Example 1: how to create a fetch function

const url = 'http://api.open-notify.org/astros.json'

const fetchurl = (url:string):void=>{

       fetch(url).then(res=>res.json()).then(jsonRes=>{
             
            console.log(jsonRes)
       })
}

fetchurl(url)

Example 2: work with fetches in js

function yourfunction() {
    return fetch(API) 
        .then(response => response.json())
        .then(data => data.content)
}
