/*

To get the list of valid language codes - do the following:
Open the following URL in your browser: https://tesseract-ocr.github.io/tessdoc/Data-Files-in-different-versions.html

Check this element is the proper table tbody with all the codes via console:
document.getElementsByTagName('table').item(0).children.item(1)

Now, copy the following code and paste it into the console:
function parseLangs() {
let langs = {};
  Array.from(document.getElementsByTagName('table').item(0).children.item(1).children).forEach((el) => {
    const [codeEl, languageEl, ...rest] = el.children
    const code = codeEl.innerText.trim()
    const language = languageEl.innerText.trim()
    if (!!code && !!language) langs[code] = language
  })
  return langs;
}

now, run the function:
copy(parseLangs())
