Description

When a condition for an if statement is true, the block of code following it is executed. What about when that condition is false? Normally nothing would happen. With an else statement, an alternate block of code can be executed.

if (num > 10) {
  return "Bigger than 10";
} else {
  return "10 or Less";
}

Instructions

Combine the if statements into a single if/else statement.

Tests

tests:
  - text: You should only have one <code>if</code> statement in the editor
    testString: assert(code.match(/if/g).length === 1);
  - text: You should use an <code>else</code> statement
    testString: assert(/else/g.test(code));
  - text: <code>testElse(4)</code> should return "5 or Smaller"
    testString: assert(testElse(4) === "5 or Smaller");
  - text: <code>testElse(5)</code> should return "5 or Smaller"
    testString: assert(testElse(5) === "5 or Smaller");
  - text: <code>testElse(6)</code> should return "Bigger than 5"
    testString: assert(testElse(6) === "Bigger than 5");
  - text: <code>testElse(10)</code> should return "Bigger than 5"
    testString: assert(testElse(10) === "Bigger than 5");
  - text: Do not change the code above or below the lines.
    testString: assert(/var result = "";/.test(code) && /return result;/.test(code));

Challenge Seed

function testElse(val) {
  var result = "";
  // Only change code below this line

  if (val > 5) {
    result = "Bigger than 5";
  }

  if (val <= 5) {
    result = "5 or Smaller";
  }

  // Only change code above this line
  return result;
}

// Change this value to test
testElse(4);

Solution

function testElse(val) {
  var result = "";
  if(val > 5) {
    result = "Bigger than 5";
  } else {
    result = "5 or Smaller";
  }
  return result;
}
