What I learned

I learnt a lot while working on this challenge, especially on APIs. I also implemented the search and filter feature beautifully, i was amazed.

Code snippets i was amazed about:

//Search feature
let searchInput = document.getElementById('search')
searchInput.addEventListener('input', () => {
  let searchValue = searchInput.value.toUpperCase()
  let cardsDB = document.querySelectorAll(".cards");

  for(let i = 0; i < cardsDB.length; i++) {
    let countryName = cardsDB[i].querySelector('h2').innerHTML
    if (countryName.toUpperCase().indexOf(searchValue) > -1) {
      cardsDB[i].style.display = ""
    } else {
      cardsDB[i].style.display = "none"
    }
  }
})

let region = document.getElementById("region")
region.addEventListener("input", () => {
  let regionValue = region.value
  let selectedRegion = data.filter(country => country.region == regionValue)
  renderDB(selectedRegion)
})

Continued development

I've gotten a lot of experience while working with web based technologies like HTML, CSS, Bootstrap, and JavaScript. It's time to take on a JavaScript framework/library, and ReactJS it is.
