An assignmentExpression assigns the value of the right-hand-side (valueExpression) to the variable, sequence element, or sequence slice referenced on the left-hand-side.

This example demonstrates sequence element, or sequence slice assignment:

var food = ['cheese', 'soda', 'fries', 'cupcake'];
println( food );
food[2] = 'eggplant';
println( food );
food[4] = 'measles';   
println( food );
food[0..1] = ['spinach', 'brocolli', 'apples'];   
println( food );
food[4..20] = 'tomatoes';   
println( food );

As a result, the following is printed on the console:

[ cheese, soda, fries, cupcake ]
[ cheese, soda, eggplant, cupcake ]
[ cheese, soda, eggplant, cupcake ]   
[ spinach, broccoli, apples, eggplant, cupcake ]   
[ spinach, broccoli, apples, eggplant, tomatoes ]   

The value of the assignment expression is the value of the variable, element, or slice after the assignment. The type of the assignment expression is the type of the variable, element, or slice.
