How to write a JS function to check if a number is odd or even or invalid? (fractions are neither odd nor even)

The input comes as a single number argument.

**Examples:**

**Input:** 5

**Output: **odd

**Input: **8

**Output: **even

**Input: **1.5

**Output: **invalid

The output should be printed to the console.

Print **odd** for odd numbers, **even** for even number and **invalid** for numbers that contain decimal fractions.
