Build a Roman Numeral Converter

Roman numerals are based on seven symbols and can be written using various combinations to represent Arabic numerals. For example: | Roman numerals | Arabic numerals | |----------------|-----------------| | M | 1000 | | CM | 900 | | D | 500 | | CD | 400 | | C | 100 | | XC | 90 | | L | 50 | | XL | 40 | | X | 10 | | IX | 9 | | V | 5 | | IV | 4 | | I | 1 | **Objective:** Build an app that is functionally similar to <a href="https://roman-numeral-converter.freecodecamp.rocks" target="_blank" rel="noopener noreferrer nofollow">https://roman-numeral-converter.freecodecamp.rocks</a>. **User Stories:** 1. You should have an `input` element with an `id` of `"number"`. 1. You should have a `button` element with an `id` of `"convert-btn"`. 1. You should have a `div`, `span` or `p` element with an `id` of `output`. 1. When you click on the `#convert-btn` element without entering a value into the `#number` element, the `#output` element should contain the text `"Please enter a valid number"`. 1. When the `#number` element contains the number `-1` and the `#convert-btn` element is clicked, the `#output` element should contain the text `"Please enter a number greater than or equal to 1"`. 1. When the `#number` element contains the number `4000` or greater and the `#convert-btn` element is clicked, the `#output` element should contain the text `"Please enter a number less than or equal to 3999"`. 1. When the `#number` element contains the number `9` and the `#convert-btn` element is clicked, the `#output` element should contain the text `"IX"`. 1. When the `#number` element contains the number `16` and the `#convert-btn` element is clicked, the `#output` element should contain the text `"XVI"`. 1. When the `#number` element contains the number `649` and the `#convert-btn` element is clicked, the `#output` element should contain the text `"DCXLIX"`. 1. When the `#number` element contains the number `1023` and the `#convert-btn` element is clicked, the `#output` element should contain the text `"MXXIII"`. 1. When the `#number` element contains the number `3999` and the `#convert-btn` element is clicked, the `#output` element should contain the text `"MMMCMXCIX"`.
