So you’ve learned how to create lists, and how to append elements to them, using the append method and the += operator.

const pastries = ['cookie', 'cupcake', 'donut', 'pie'];

print(pastries[0]);

print(pastries[100]);

var morePastries = pastries.sublist(1, 3);
print(morePastries);

morePastries.clear();
print(evenmMorePastries);

print(evenMorePastries.isEmpty);

print(pastries[0]);

print(pastries.first);

print(pastries.last);

print(pastries.length);

print(pastries.contains('cookie'));

print(pastries.contains('lasagna'));

var pastries = ['cookie', 'cupcake', 'donut', 'pie'];

pastries.add('brownie');
print(pastries);

pastries[4] = 'cream puff';

pastries.insert(1, 'tart');

print(pastries);

var pastry = pastries.removeAt(0);
print(pastry);
