Insights into Null Coalescing Operator and If Conditions for Faster Coding

#learning #productivity

I thought the null coalescing operator was limited to something like:

null ?? 'show this value';
undefined ?? 'show that value';

However, it surprised me that we can actually chain and use it multiple times, as in:

null ?? undefined ?? 'show this value';

While this chaining capability exists, it's not always recommended. Typically, for the sake of readability, a more explicit 'if' condition would be preferable. But, it might be handy and preferable for a concise single line of code.

And speaking of 'if' condition, I also learned that we could use a single line of code for both 'else if' and 'else' (without curly braces), as demonstrated in the image below.
