Remove a specific item in an array either the mutating way or the non-mutating way.
//Mutating way
const muatatedArray = ['a','b','c','d','e'];
muatatedArray.splice(2,1)
console.log(muatatedArray) //['a','b','d','e']
//Non-mutating way
const nonMuatatedArray = ['a','b','c','d','e'];
const newArray = nonMuatatedArray.filter((item, index) => !( index === 2 ));
console.log(newArray) //['a','b','d','e']Source
