56533eb9ac21ba0edf2244da Introducing Else Statements 1 https://scrimba.com/c/cek4Efq 18207 introducing-else-statements

--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.

--hints--

You should only have one if statement in the editor

assert(code.match(/if/g).length === 1);

You should use an else statement

assert(/else/g.test(code));

testElse(4) should return the string 5 or Smaller

assert(testElse(4) === '5 or Smaller');

testElse(5) should return the string 5 or Smaller

assert(testElse(5) === '5 or Smaller');

testElse(6) should return the string Bigger than 5

assert(testElse(6) === 'Bigger than 5');

testElse(10) should return the string Bigger than 5

assert(testElse(10) === 'Bigger than 5');

You should not change the code above or below the specified comments.

assert(/let result = "";/.test(code) && /return result;/.test(code));

--seed--

--seed-contents--

function testElse(val) {
  let 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;
}

testElse(4);

--solutions--

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