if

Often code should only be executed if a certain condition is true. To do this, use the if statement.
var win = 0;
if (dice === 6) {
  win = 100;
}
This statement consists of the keyword if followed by parentheses. The parentheses contain an expression - the condition - that is evaluated to true or false. If the condition results in true, all statements in the block delimited by the curly brackets will be executed. If the condition results in false, the block bounded by the curly brackets will be skipped. In our example, if dice has the value 6, then win is set to 100. If dice does not have the value 6, then win remains at 0.

Exercise

Write a function equals that checks two values for strict equality. If the two values are equal, the string 'EQUAL' should be returned. If they are unequal, you should get 'UNEQUAL'. The call equals(1, 1) should return 'EQUAL', the call equals(1, 2) should return 'UNEQUAL'.
