feeling lucky

tl;dr guessing / poking around in the dark / deleting everything has never worked and if it has it's infinitely less preferable to the ^ method

feeling lucky is almost always right, if howdoi didn't quite get you there

1. edit ur search engine settings to include a shortcut to i'm feeling lucky query
2. mine being l <space> "query"
3. read the resulting page and weep

my own experiences in debugging (to tears) and watching other developers is the immediate googling of a well-ish worded question will produce the intended result

bonus tip: this is failsafe provided that you've clearly defined distinct steps you need to take & make it happen

double bonus: reading documentation

triple bonus: reading and then practicomg what u read in a sandbox

quadruple bonus: spaced repetition of 1-3

stats

NB chrome doms & reses r as follows:

browser extensions

octomate, octolinker

adds shiny download button to download files, a TOC, and favorites bar

octomate (opens new window), octolinker (opens new window)

klim reader

prettier even than Safari which is second prettiest

note to self: you can find stylesheets for extensions the same way as any other (n it might be well-commented too)

simplest example yet mb the most informative of any bookmarklet (second maybe to Axe for accessibility)

javascript:
  window.location=`
    https://uitest.com/en/check/results/?url=${window.location}
  `

html code sniffer

tests 4 different standards (WCAG2[A]AA, standard 508), with links on how to pass on the relevant whatwg guideline

javascript: (function () {

textise:
