@fratting Appears to be a variety of problems, one of which is the tryCatcher function executing a function called 'bound error'. the target var is the source of the illegal character. Another instance is the console.warn at like 1546 of the unminified bluebird.js file. console is considered an illegal character. Odd and only with firefox
Also, "Promise.config is not a function", and "Promise is not a constructor"
What is the license for the code snippets in the Bluebird's Wiki, more specifically the Optimization killers?
Thank you
Thank you
Basically was hoping Promise.map().then() would run after all the mapped promises, however the then is running immediately.

So I would hope for the indexes to be built after the save operations, but it's happening immediately.
Beautiful, that was it, thank you so much! The pain that has saved me :D
here's my "not" working example:
resultSet.map( item => {
Promise.coroutine( function* (user) {
let opt = {
TableName: 'tableName',
KeyConditions: {
username: {
AttributeValueList: [user],
ComparisonOperator: 'EQ'
}
},
ProjectionExpression: 'firstname, lastname',
}
let userFriends = yield dynamodb.queryAsync(opt)
/* random code here to assign first name and last name to item */
})(item);
return item
});
@danyextreame_twitter Are you sure? I don't see any notice in the docs and seems to work fine with a quick test in https://npm.runkit.com/bluebird
these methods could be called switchIfEmpty thenIfEmpty trowIfEmpty
this would be useful after a database query, after making a filter, to return an error such as, User Not Exist, Password Not Match, or return a default object
This is admittedly pretty random. Do with it what you will and interpret it however you see fit, but here goes: I have been paid to write about topics I know nothing about since I was 15 years old. I've managed the knowledge base for a global payments fraud platform, nuclear reactors, and offshore oil rigs. In April of 2019, I couldn't articulate how a "stock" differs from a "share". By May of 2019, I was publishing gated content which was (A) full of speaking
^^^ sorry, pressed enter too early (A) full of math, and (B) designed to speak specifically to the heads of venture capital firms. I say all this for context. Because until I emerged on the other side of an internet rabbit hole, looked around, and saw this: http://bluebirdjs.com/docs/why-promises.html
I cannot remember the last time I was fully just unable to take so much as a GUESS about what I was reading 😆 in all these years, I don't think I've ever come across a full webpage worth of content that was as "inside baseball" as this. I mean...this has to pretty esoteric even to, like, a career software developer, right?
why might I want to set
concurrency = 1 and only allow one function at a time?

Hi guys, can someone help me with this: https://stackoverflow.com/questions/68480888/how-to-stop-a-promise-map-execution-after-an-error-with-bluebird
there are several similar questions around but no one found a working solution yet
I'd like to replace the
.then()/.catch() syntax with async/await/throw.
Does Bluebird support async/await?
http://bluebirdjs.com/docs/features.html#async-await is not yet written.
Second, the reason I used BB in 2018 was its support for Promise.using() and disposers. I'm now trying to find out if this feature ever made it into standard ES2016+. Does anyone know?
I want return a Bluebird on a async function.
