In TypeScript, I often prefer to use a Record over a switch statement
In TypeScript, I often prefer to use a Record over a switch statement.
✅ It's easy to read.
✅ It's typically less code.
✅ It's safer. With a switch, I have to do extra work to assure it's exhaustive. With a Record, if I forget to handle a case, it won't compile.
When I forget a case with a Record, I get a helpful compile-time message.
With a switch, I need to remember to code it in a manner that's exhaustive (such as throw in the default).
So a Record is safer.
