Sequelize 7 example gives error "Invalid or unexpected token"

[ricklrq]

Tried to run the quick example (https://sequelize.org/docs/v7/), got error.

@Attribute(DataTypes.STRING)
  ^
SyntaxError: Invalid or unexpected token

I am using Javascript.

That's the decorator syntax, you currently need a transpiler to use it: https://sequelize.org/docs/v7/models/defining-models/#defining-a-model-1

After transpiling the decompiled code to compiled using babel

npx babel db/models/languages.js --out-file db/models/transpiledLanguages.js

It return error, when i try to use my model

import { Languages } from '../../db/models/transpiledLanguages.js'

args[2] ?? Object.getOwnPropertyDescriptor(args[0], args[1])
^

TypeError: Cannot convert undefined or null to object
