hello i am quite new to javascript (im coming from python and i love d.js already)
i have this class ```javascript
class LocalSlashBuilder {
constructor() {
this.data = [];
this.interactionMap = {};
}

register(name, description, callback) {
    this.data.push({name: name, description: description});
    this.interactionMap[name] = callback;
}

dispatch_for(name, interaction) {
    this.interactionMap[name](interaction);    
}

}
``` the issue is, in dispatch_for the expression doesnt work, it says that: TypeError: this.interactionMap[name] is not a function
though upon googling i dont see anything wrong
this is also how i would write this in python
i have no idea why this happens

are you sure this.interactionMap[name] isn't undefined?

could log the map and name and see if they're what you expect

fallen sparrow

thats what i suspect but how come?

patent jackal

how come what?

it's undefined?

dispatch_for(name, interaction) {
    console.log(`Requesting interaction response for ${name}`);
    const callback = this.interactionMap[name];    
    console.log(callback, typeof callback);
    callback(interaction);
}
``` ill test this

well discord wouldn't, it'd mean that there's some issue with how you're registering/dispatching that "builder"

fallen sparrow

i wonder if im accessing it incorrectly

patent jackal

log interaction

it's probably not an interaction

fallen sparrow

the attribute is commandName and not name
