+# Exercise 13 - analyzeNumber
+
+Description of the exercise goes here.
+
+## Task
+
+Write a function `analyzeNumber` that takes a single number as an argument and returns an object with two properties:
+
+1. `type`: A string indicating whether the number is `"positive"`, `"negative"`, or `"zero"`.
+2. `parity`: A string indicating whether the number is `"even"` or `"odd"`.
+
+### Examples
+
+```javascript
+analyzeNumber(5); // { type: "positive", parity: "odd" }
+analyzeNumber(-8); // { type: "negative", parity: "even" }
+analyzeNumber(0); // { type: "zero", parity: "even" }
+
+
+---
+
+### 2. **`analyzeNumber.js`**
+
+```javascript
+function analyzeNumber(number) {
+  let type;
+
+  if (number > 0) {
+    type = 'positive';
+  } else if (number < 0) {
+    type = 'negative';
+  } else {
+    type = 'zero';
+  }
+
+  const parity = number % 2 === 0 ? 'even' : 'odd';
+
+  return { type, parity };
+}
+
+module.exports = analyzeNumber;
