Declaring variables and not using them

[crianonim]

For example: handler.js: line 5

const env = require("dotenv").config();

Since you never use env you do not need to create a global variable

[dubhcait]

ya can just write

require("dotenv").config();

Plus further down line 46 const newsKey = process.env.DBAPIKEYNEWS; DB is usually used for databases, not APIs, it's just naming convention.
