//Reduce

//Push
['🀬', '😑', 'πŸ™‚', '😊'].push('πŸ˜„') = 5 // it will insert 'πŸ˜„' to list at last

//unshift
['😑', 'πŸ™‚', '😊', 'πŸ˜„'].unshift('🀬') = 5 // it will insert '🀬' to list at first

//Pop
['🀬', '😑', 'πŸ™‚', '😊', 'πŸ˜„'].pop('πŸ˜„') = 'πŸ˜„' // it will remove 'πŸ˜„' from list

//Shift
['🀬', '😑', 'πŸ™‚', '😊', 'πŸ˜„'].shift() = '🀬' // it will remove '🀬' from list

//Reverse
