How to write accessible code?

1. Group code blocks in a logical way:

   • Keep your variables close to where they are used.

2. Use short names:

   • Naming a variable “a” or “b” is fine.
   • But … I lose context, right? … DO NOT! If you respect rule 1, there is no problem, you will reduce the redundancy and the cognitive load of your code.

3. Use names that speak for themselves:

   • Nothing of “mVal”, “tRows”, etc …

4. Use the new lines intentionally:

   • In the same way that you divide a text into paragraphs, make the new lines in your code communicate something.

That first rule is so important. Trying to read a part of a long function (a problem in itself) but ALL of the variables are declared at the beginning of the function. Then you have to read a line, scroll up to figure out the variables, then scroll back down and find your place.

Exhausting.
