let myFish = ['angel', 'clown', 'mandarin', 'sturgeon']
let removed = myFish.splice(2, 0, 'drum')
// myFish is ["angel", "clown", "drum", "mandarin", "sturgeon"]
let words: string[] = [
'What',
'I',
'do',
'create,',
'I',
'cannot',
'not',
'understand.',
];
let newWords = words.splice(2, 1, 'cannot');
let newWords2 = words.splice(5, 2, 'do not');
//console.log(newWords);
console.log(words.join(' '));
//What I cannot create, I do not understand.
