The basic format of the assignment operator is:
x = 6;
The assignment operator can also be stacked to create simultaneous assignments.
x = y = z = 6;
Multiple assignment operators are evaluated from right to left.
y = (x = 3) + 4;
the value 3 is assigned to the variable x, which is then added to the value 4 and assigned to the variable y.
Once the expression is fully evaluated, y will contain the value 7.
