why set event return type to void instead of any?

Client.on("messageCreate", async (Message) => {
    let isWrongAns = ...

    if (isWrongAns) return await Message.channel.send("wrong answer");
})

Client.on("messageCreate", async (Message) => {
    let isWrongAns = ...

    if (isWrongAns) return await Message.channel.send("wrong answer");
})

typescript error (simplified):

the "messageCreate" event's expected return type is Promise<void>. But since you are returning a Message, i am giving you this error

the "messageCreate" event's expected return type is Promise<void>. But since you are returning a Message, i am giving you this error

i didnt use typescript before djs v14 but why not set the type to Promise<any>? is there a specific reason

Unless im missing something, arent you the one that can change what the function will expect to receive? If you want to to receive Promise<any>, just put it

(param1, param2): returnType => {}

u mean changing the callback to something like

Client.on("messageCreate", async function (Message): Promise<any> {
    let isWrongAns = ...

    if (isWrongAns) return await Message.channel.send("wrong answer") as any as Promise<any>;
})

Client.on("messageCreate", async function (Message): Promise<any> {
    let isWrongAns = ...

    if (isWrongAns) return await Message.channel.send("wrong answer") as any as Promise<any>;
})

yea mb i typed wrong but thats just unnecessary complication

Parogo_72•2y ago

Doubt you need as any as Promise<any> Else you can also do Promise<Message> if you will always return a message
