Discussion on: Error Handling in JavaScript (Golang Style)

[Bibek]

Yeah, that is right. But in case of multiple blocks in the same scope it can create issue, as you will not be able de-structure it like this

const {error, result} = await method();

// second method call will create an issue
const {error, result} = await method2();

But in case of array, you can use other variable name in the second method call.

Feel free to correct me, if I am missing something.

[Brendan Mullins]

a few ways you could avoid this:

const responseOne = await methodOne();
if (responseOne.error) return

const responseTwo = await methodTwo();
if (responseTwo.error) return

// of if you want destructuring
const {error: methodOneError, result: resultOne} = await methodOne();
if (methodOneError) return
const {error: methodTwoError, result: restultTwo} = await methodTwo();
if (methodTwoError) return

Im not saying the array descructuring is worse, its just a prefference

You can rename the variable when destructuring an object.

const {error, result} = await method();

const {error: error2, result: result2} = await method2();

@jsnanigans Yeah, It's just a preference.

@erikhofer I am aware of that.
