ooh ooh me next(smth for c++) if u can

[cs6413110]

const ignore = ["the","of","in","from","by","with","and", "or", "for", "to", "at", "a"]; function generateBC(url, separator) { let src = 'HOME'+separator; const paths = url.split('/').slice(1); for (const path of paths) { let parsed = path.split('#')[0].split('?')[0]; if (parsed.length > 30) parsed = parsed.split('-').reduce((a, c) => a+c.split('')[0].toUpperCase(), ''); console.log(parsed); } }

uhm givme 2 periods

[LostKing73]

oka

[LostKing73]

i literally have looked at one slide of a like 2 day long lesson plan so surely I got it

[cs6413110]

https://www.codewars.com/kata/563fbac924106b8bf7000046/train/javascript

const ignore = ['THE','OF','IN','FROM','BY','WITH','AND','OR','FOR','TO','AT','A'];

  let src = '<a href="/">HOME</a>'+separator;
  if (paths.length === 0) return '<span class="active">HOME</span>';
  if (paths[paths.length-1].split('#')[0].split('?')[0].split('.')[0] === 'index') paths.pop();
  paths = paths.filter(a => a !== '');
  if (paths.length === 0) return '<span class="active">HOME</span>';
  let pathage = '';
  for (const path of paths) {
    let last = path === paths[paths.length-1], parsed = path.split('#')[0].split('?')[0].toUpperCase();
    if (parsed.length > 30) parsed = parsed.split('-').filter(a => !ignore.includes(a)).reduce((a, c) => a+c.split('')[0], '');

AHHHHHH MY EYES

Literally just do:

const formatDuration = t => {
  if (!t) return 'now';
  let y, d, h, m, s, msg = '';
  let time = [t%60, Math.floor(t/60)%60, Math.floor(t/(60*60))%24, Math.floor(t/(60*60*24))%365, Math.floor(t/(60*60*24*365))];
  for (let i = 4; i >= 0; i--) {
    if (time[i] && msg.length > 0 && time.slice(0, i).join('').replace(/0/g, '').length === 0) msg = msg.slice(0, -2)+' and ';
    if (time[i]) msg += time[i]+' '+['second', 'minute', 'hour', 'day', 'year'][i]+(time[i] > 1 ? 's' : '')+', ';
  }
  return msg.slice(0, -2);
}
