Description

If you have multiple conditions that need to be addressed, you can chain if statements together with else if statements.

if (num > 15) {
  return "Bigger than 15";
} else if (num < 5) {
  return "Smaller than 5";
} else {
  return "Between 5 and 15";
}

Instructions

Convert the logic to use else if statements.

Tests

tests:
  - text: You should have at least two <code>else</code> statements
    testString: assert(code.match(/else/g).length > 1);
  - text: You should have at least two <code>if</code> statements
    testString: assert(code.match(/if/g).length > 1);
  - text: You should have closing and opening curly braces for each <code>if else</code> code block.
    testString: assert(code.match(/if\s*\((.+)\)\s*\{[\s\S]+\}\s*else if\s*\((.+)\)\s*\{[\s\S]+\}\s*else\s*\{[\s\S]+\s*\}/));
  - text: <code>testElseIf(0)</code> should return "Smaller than 5"
    testString: assert(testElseIf(0) === "Smaller than 5");
  - text: <code>testElseIf(5)</code> should return "Between 5 and 10"
    testString: assert(testElseIf(5) === "Between 5 and 10");
  - text: <code>testElseIf(7)</code> should return "Between 5 and 10"
    testString: assert(testElseIf(7) === "Between 5 and 10");
  - text: <code>testElseIf(10)</code> should return "Between 5 and 10"
    testString: assert(testElseIf(10) === "Between 5 and 10");
  - text: <code>testElseIf(12)</code> should return "Greater than 10"
    testString: assert(testElseIf(12) === "Greater than 10");

Challenge Seed

function testElseIf(val) {
  if (val > 10) {
    return "Greater than 10";
  }

  if (val < 5) {
    return "Smaller than 5";
  }

  return "Between 5 and 10";
}

// Change this value to test
testElseIf(7);

Solution

function testElseIf(val) {
  if(val > 10) {
    return "Greater than 10";
  } else if(val < 5) {
    return "Smaller than 5";
  } else {
    return "Between 5 and 10";
  }
}
