+# --description--
+
+In this lab you will build an odd Fibonacci sum calculator that computes the sum of all odd Fibonacci numbers that are less than or equal to a given positive integer.
+
+**Objective**: Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories**
+
+1. You should have a `sumFibs` function that accepts a number as an argument.
+1. The `sumFibs` function should return the sum of all odd Fibonacci numbers that are less than or equal to the given number.
+1. The Fibonacci sequence starts with `0` and `1`, and each subsequent number is the sum of the two previous ones.
+1. Only the odd Fibonacci numbers should be added to the sum.
+
+# --hints--
+
+You should have a `sumFibs` function.
+
+```js
+assert.isFunction(sumFibs);
+```
+
+`sumFibs(1)` should return a number.
+
+```js
+assert.isNumber(sumFibs(1));
+```
+
+`sumFibs(1000)` should return `1785`.
+
+```js
+assert.strictEqual(sumFibs(1000), 1785);
+```
+
+`sumFibs(4000000)` should return `4613732`.
+
+```js
+assert.strictEqual(sumFibs(4000000), 4613732);
+```
+
+`sumFibs(4)` should return `5`.
+
+```js
+assert.strictEqual(sumFibs(4), 5);
+```
+
+`sumFibs(75024)` should return `60696`.
+
+```js
+assert.strictEqual(sumFibs(75024), 60696);
+```
+
+`sumFibs(75025)` should return `135721`.
+
+```js
+assert.strictEqual(sumFibs(75025), 135721);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+function sumFibs(num) {
+  let a = 0, b = 1;
+  let sum = 0;
+
+  while (b <= num) {
+    if (b % 2 !== 0) {
+      sum += b;
+    }
+    [a, b] = [b, a + b];
+  }
+
+  return sum;
+}
+```
