Javascript would have no problem with it. Semicolons are already kinda optional in there, and having tons of question marks in your code is also pretty normal. ie:

input?.map(item => !!item?.name ? item : item?.toString() ?? "New Item")

Just means: If the variable named "input" has a function named .map(), which is usually the case if it's an array, you go through that array and transform its elements in the following way:

• is your element an object that has the property "name" and that property isn't undefined, null or 0? (the "!!" is a double negation that would force undefined, null and 0 to evaluate to false through type coercion)?

• if yes ( the syntax " ___ ? ___ : ___ " is a shorthand for an if-else statement) then just add that whole item to your output array.

• if not, try to call the .toString() function on your item. If that works then that's your result, if not then your output is the string "New Item" ( the "??" is called the nullish coalescing operator - if the left side of the ?? evaluates to undefined or null, it takes the right--hand side value instead. The "?." part is called optional chaining and will evaluate to undefined if you try to call a function that doesn't exist on that type)

• oh yeah, and if input isnt an array to begin with and doesn't have a .map() function? We just do nothing and move on without complaining. JS truly does not give a fuck.

Interesting. For me it's the opposite, I can't see any difference in the fixed width font, but it's different in the variable width one.

Fonts. Full of mysteries.

For me:

You should see if it detects and highlights the difference between the two.

Semicolon or question mark?
