node_modules/discord.js/typings/index.d.ts(267,40): error TS2689: Cannot extend an interface 'Map'. Did you mean 'implements'?

[mlagarrigue]

it happens when compiling my ts project

you should just change export class Collection<K, V> extends Map<K, V> { into export class Collection<K, V> implements Map<K, V> { here is my tsconfig

{
    "compilerOptions": {
      /* Basic Options */

i think this belongs to The Official typings repo of Discord.js rather than to d.js repo itself

[mlagarrigue]

I created an issue on there github too,

do you confirm I can close here ?

[DevYukine]

yes you can close this now :)
