So really interesting to read the presumptions. Then I want to create clarity. So TypeScript is meant to write versions with higher JavaScript (ES6 or higher). Babel uses it to compile back into a javascript which most browsers understand, e.g. ES5 but I would not specify an explicit version but specify how many versions he should compile back or make compatible.

Show my tutorial:
JavaScript scales with TypeScript
Or use my NPM package and generate:
Generator Webpack Preact (NPM)
Generator Webpack Preact (Github)

tsconfig.json
Here is the target for TypeScript and is it ES6

{
    "compilerOptions": {
        "target": "es6",
    },
}

.babelrc
And here is ES5

{
    "presets": ["es2015"],
}

But we can do this:
.babelrc

{
        "presets": [
            [
                "env",
                {
                    "targets": {
                        "browsers": [
                            "last 2 versions",
                            "safari >= 7"
                        ]
                    }
                }
            ]
        ],
},

Or this
package.json

"babel": {
        "presets": [
            [
                "env",
                {
                    "targets": {
                        "browsers": [
                            "last 2 versions",
                            "safari >= 7"
                        ]
                    }
                }
            ]
        ],
},

Of course you should not do that in runtime, but in your development environment you should not have any performance losses.
