rest-countries-api-with-color-theme-switcher with React and Sass

Everything looks great, but in small details you need to add a "all" option in the filter, I can't recover all the countries when set a continent and also you could add some pagination like Infinite scroll that way all the countries doesn't load at the same time.

try to use another endpoit of the api to use the borders alpha code to solve the HTML errors

and last but not least axios is a good library you could use for fetching data from the api, you could set a baseurl and that way you don't need to sent the entire url, just the endpoit for example {{baseurl}}"/api/data"
