switch statement. A switch statement tests a value and can have many case statements which define various possible values. Statements are executed from the first matched case value until a break is encountered.
Here is a pseudocode example:
switch(num) {
case value1:
statement1;
break;
case value2:
statement2;
break;
...
case valueN:
statementN;
break;
}
case values are tested with strict equality (===). The break tells JavaScript to stop executing statements. If the break is omitted, the next statement will be executed.
val and sets answer for the following conditions:1 - "alpha"2 - "beta"3 - "gamma"4 - "delta"
caseInSwitch(1) should have a value of "alpha"
testString: assert(caseInSwitch(1) === "alpha", 'caseInSwitch(1) should have a value of "alpha"');
- text: caseInSwitch(2) should have a value of "beta"
testString: assert(caseInSwitch(2) === "beta", 'caseInSwitch(2) should have a value of "beta"');
- text: caseInSwitch(3) should have a value of "gamma"
testString: assert(caseInSwitch(3) === "gamma", 'caseInSwitch(3) should have a value of "gamma"');
- text: caseInSwitch(4) should have a value of "delta"
testString: assert(caseInSwitch(4) === "delta", 'caseInSwitch(4) should have a value of "delta"');
- text: You should not use any if or else statements
testString: assert(!/else/g.test(code) || !/if/g.test(code), 'You should not use any if or else statements');
- text: You should have at least 3 break statements
testString: assert(code.match(/break/g).length > 2, 'You should have at least 3 break statements');
