[NFBCS] Reading JavaScript with a Braille Display

[Lewis Wood]

I make it a rule that all closing tags, braces are line commented with openers.

For example:

If (isLink€ ) {
varl = "";
 
Myarray.map( € => {
} // if isLink
L = `<a href="$O{e.address}"> e.text</a>`;

} //if isLink
Else { 
 L = e.text;
} // else
Return ` <li>${l}</li>`;
}); // myArray.map


When I need to understand or follow code I reformat it. We blind can only process 11 line at a time. So getting lost is a constant struggle. 
I did a map, since you are apparently studying a reduce function. 
Hope this demonstrates the difference and how you can make it easier to understand.

Subject: [NFBCS] Reading JavaScript with a Braille Display

Hi all,

 

I'm working on a group of exercises which demonstrate functional programming in JavaScript. The concept is understandable, but I am having trouble reading the code samples using a Mantis Braille display with NVDA. Here's an example. I am working with an object and need to use the reduce method on a key in the object which contains numeric data. I'm supposed to return an average rounded to the nearest whole number. When I look at an example, the use of parentheses and braces is very nested. There are multiple return statements as well as arrow functions, and parameters. All these things are spread out over about a dozen lines. The solution makes sense but reading the sample is almost impossible. It's difficult to keep track of how each parenthesis or brace is opened and closed.

 

I used to be a mainframe programmer and ran into the same issues but got used to reading and writing code using a Braille display with JAWS. I don't think there are accessibility issues it's just a matter of my ability to put the entire picture together as I am reading. Do any of you have any suggestions?

 

Thanks,

Dan
