8. ES8 #

Created Friday 17 July 2020

Important changes in 2017:

1. String functions for adding spaces to the end(s).
   • myString.padStart(targetLength, fillUnit)
   • myString.padStart(20, '*') Output: ******8273
   • myString.padEnd(20, 'x'); Output: Angry Birdsxxxxxxxxx
2. Trailing comma is ignored - in iterables, objects, functions(call and definition). But avoided repeated commas in arrays, otherwise empty elements will be created.
3. Object iteration key, value or both:
   • Object.keys(student) - existing feature.
   • Object.values(student) - returns an array of values.
   • Object.entries(student) - returns an array of key value pairs(as arrays of size 2). Note: Object class is used here.
4. Async Await - FIXME

Note:

• "my String".trim() trims the whitespace at the ends.
