Example: live search using fetch api
const search_input = document.getElementById('search');
const results = document.getElementById('results');
let search_term = '';
let countries;
const fetchCountries = async () => {
countries = await fetch(
'https://restcountries.eu/rest/v2/all?fields=name;population;flag'
).then(res => res.json());
};
const showCountries = async () => {
results.innerHTML = '';
await fetchCountries();
const ul = document.createElement('ul');
ul.classList.add('countries');
countries
.filter(country =>
country.name.toLowerCase().includes(search_term.toLowerCase())
)
.forEach(country => {
const li = document.createElement('li');
li.classList.add('country-item');
const country_flag = document.createElement('img');
country_flag.src = country.flag;
