For Task one was it ok for me to add another country by using the push method? I saw another video on UDEMY and I wanted to wing it and referenced then applied it on this task. I prefer doing your task as suppose to the UDEMY one I am currently learning.

let countries = ['Romania', 'UK', 'Philippines']
const newLength = countries.push('Austria');

console.log(countries);
