Destructuring the console object
Just as we can destructure all other objects, we can destructure functions like log() and warn() directly out of the console object.

Read fire tipRelative timestamps with Intl
JavaScript
JavaScript has a built-in formatter for relative timestamps. It returns strings like “yesterday” or “2 months from now” in the language you specify.
This does not currently work in IE and Safari.
// a positive value describes a time in the future
new Intl.RelativeTimeFormat('en').format(2, 'day')
// ⇒ 'in 2 days'
// a negative value describes a time in the past
new Intl.RelativeTimeFormat('en').format(-1, 'day')
// ⇒ '1 day ago'
// `numeric: 'auto'` results in strings like “yesterday” and “tomorrow”
new Intl.RelativeTimeFormat('en', { numeric: 'auto' }).format(-1, 'day')
// ⇒ 'yesterday'
// the formatter can base its output on different languages
new Intl.RelativeTimeFormat('de').format(3, 'month')
// ⇒ 'in 3 Monaten'
