5690307fddb111c6084545d7 Logical Order in If Else Statements 1 https://scrimba.com/c/cwNvMUV 18228 logical-order-in-if-else-statements

--description--

Order is important in if, else if statements.

The function is executed from top to bottom so you will want to be careful of what statement comes first.

Take these two functions as an example.

Here's the first:

function foo(x) {
  if (x < 1) {
    return "Less than one";
  } else if (x < 2) {
    return "Less than two";
  } else {
    return "Greater than or equal to two";
  }
}

And the second just switches the order of the statements:

function bar(x) {
  if (x < 2) {
    return "Less than two";
  } else if (x < 1) {
    return "Less than one";
  } else {
    return "Greater than or equal to two";
  }
}

While these two functions look nearly identical if we pass a number to both we get different outputs.

foo(0)
bar(0)

foo(0) will return the string Less than one, and bar(0) will return the string Less than two.

--instructions--

Change the order of logic in the function so that it will return the correct statements in all cases.

--hints--

orderMyLogic(4) should return the string Less than 5

assert(orderMyLogic(4) === 'Less than 5');

orderMyLogic(6) should return the string Less than 10

assert(orderMyLogic(6) === 'Less than 10');

orderMyLogic(11) should return the string Greater than or equal to 10

assert(orderMyLogic(11) === 'Greater than or equal to 10');

--seed--

--seed-contents--

function orderMyLogic(val) {
  if (val < 10) {
    return "Less than 10";
  } else if (val < 5) {
    return "Less than 5";
  } else {
    return "Greater than or equal to 10";
  }
}

orderMyLogic(7);

--solutions--

function orderMyLogic(val) {
  if(val < 5) {
    return "Less than 5";
  } else if (val < 10) {
    return "Less than 10";
  } else {
    return "Greater than or equal to 10";
  }
}
