When it comes to writing functions with numerous parameters, do you typically format them like this:
function foo(
a: number,
b: string,
c: boolean): boolean {
....
}
or do you prefer formatting them like this:
function foo(
a: number,
b: string,
c: boolean
): boolean {
....
}
Which style do you lean towards?
Although the way code is formatted can be a matter of personal style, it's worth considering one thing:
let c: number = 10
function foo(
a: number,
b: string) {
c = 123
}
It's clear that this formatting can lead to confusion between the parameter list and the beginning of the code block. I used to format my code like this too, but now I'm thinking of switching to
function foo(
a: number,
b: string)
{
c = 123
}
// or, for a more JavaScript-friendly approach
function foo(
a: number,
b: string
) {
c = 123
}
Ultimately, the best formatting choice comes down to personal preference and what works best for your team.
