Sometimes it is easier to use a boolean flag as a function argument, if splitting the function would result in two almost identical functions. But rather than pass in a boolean, I like to give a unioned string option in TypeScript which is descriptive of what the flag means:
functionloadSchema(schema:Schema,sync:'sync'|'async'){// }// One eterminty later...loadSchema("...",'sync')
Yeah, nothing is set in stone. If you feel like this is appropriate, go for it. In my opinion it's much better than a boolen flag already. If you are using TypeScript this is a good alternative. However, for JavaScript I won't recommend this, as you could do the following:
loadSchema("…","fast")
At first glance it's not obvious that "fast" is an invalid argument here.
