How do I make Object.entries available in TypeScript? [duplicate]

Question

In my angular-cli-built app (which is currently using TypeScript 2.0.3) I want to be able to use this decomposition-based iterator:

for (let [key, value] of Object.entries(obj)) {

}

What do I have to do in order to have it recognized:

• upgrade TypeScript?
• use a polyfill?
  • if so: how do I import it - in individual .ts files or in a config file to make it globally available?
• use a third-party library?

You need to add

"lib": [ "es2017.object" ]
