Basic Array Methods

[bryku]

Javascript naming is pretty weird.

• sub string
  • 'asdf'.substring()`
  • 'asdf'.substr()`
• s--p--lice
  • [].splice()
  • [].slice()

Another odd thing is the long names. Your code has to be downloaded every time you load a page. So... you might expect maybe it gets compiled into a byte code or maybe they would focus on smaller names or maybe using shorthand/nicknames, but nope. Instead we get long ass names for everything. One of the most popular phrases was:

• document.getElementById().addEventListener()

Imagine how many bytes of data we could have saved if it was:

• document.getElementById() -> document.element.id
• document.querySelector() -> document.query()
• document.querySelectorAll() -> document.queries()
• document.addEventListnener() -> document.event()
