## Harder, bigger, bolder, stronger

### Instructions

Being stuck at home, bored, desperate and coming up with a lot of weird ideas, a friend asks you to develop a tool to measure his ocular skills: one of those [Monoyer charts](https://en.wikipedia.org/wiki/Monoyer_chart) that ophthalmologists use.

Generate a board where each new letter is harder, bigger, bolder and stronger!

Write the function `generateLetters` which creates 120 `div`, each containing a letter randomly picked through the **uppercase** alphabet, and whose style properties have to be increased:

- each letter `font-size` has to grow from `11` to `130` pixels
- `font-weigth` has to be `300` for the first third of the letters, `400` for the second third, and `600` for the last third

### Provided files

You have at your disposal the following file that you can download to test locally:

- the HTML file [index.html](/public/subjects/harder-bigger-bolder-stronger/index.html) to open in the browser, which includes:

  - the JS script running some code, and which will also allow to run yours
  - some CSS pre-styled classes: feel free to use those as they are, or modify them
