Answer 1

You can use for ... of in TypeScript if you add "es6" as "lib" in your compiler options, and "es6" as target. You may also use "es2015.iterable" in place of "es6" in your lib if that better suits your needs.

For example (this would be your tsconfig.json):

{
    "compilerOptions": {
        "target": "es6",
        "lib": [
            "es6",
            "dom"
        ]
    },
    "exclude": [
        "node_modules"
    ]
}
