I’m having issues with a piece of code that I’ve copied below. When I run the code, I am getting a number count for each of the unnecessaryWord variables that is three times higher than it should be. The code is functioning as intended, but when it comes to a word that is included in the unnecessaryWords array, it counts three times and I’m not sure why. I realize I could set it so (betterWords[i] === ‘very’) or one of the other two, and it would probably fix it, but I’m really trying to tie the comparison to the unnecessaryWords array.
Any advice would be appreciated.
Edit: I tried using the literal array value that I’m trying to count and it still counts it three times so I really don’t know what’s wrong now.
Edit2: I figured it out. My second for loop was unnecessary with the else/if statements and was causing it to loop.
Great that you discovered the issues. It would be interesting to see how you’ve resolved this. Please share a new gist.
if A == false
not A == true
if ( ! unnecessaryWords.includes(word) )
Such an expression lets us leverage truthiness and not make direct comparisons to booleans. It’s a different twist on the original logic that alters nothing. It reads toward truthy, as opposed to falsy.
Minor constructs such as this can benefit from a “pillow to pound weight comparison”. Which is easier to understand? The more positively definitive, one would venture.
It kind of clicked in my head as soon as I asked for help with it. I banged it around in my head all day and couldn’t figure it out, but as soon as I started explaining the problem it seemed really obvious what the problem was, even though I’m still not entirely sure exactly why it was causing the problem.

I understand what you’re saying here, and I think I used .includes in the proper way further down in the code, but at the time I was writing it, making unnecessaryWords.includes… === false seemed to make the most sense. So, you’re saying that I should not be making .includes directly === to true or false in the best usage practice?

I don’t know that it relates to best practice, but it is simpler. Think truthy, not true, and falsy, not false. We never need to make a literal comparison to a boolean, just test the expression (a value) for truthiness.
Only a truthy expression or value will make into the first branch of an if statement or into the loop of a while statement. We don’t need to see the actual boolean, only the outcome of the evaluation by which branch is followed.
“Pillow to pound weight comparison” is a made up expression of mine that is essentially a comparison of complex to simple, code heavy to code light. If something looks messy (pillow), then it can be made to look less messy (pound weight).
