Choosing between ES6 or TypeScript for migrating to Angular 2?

Our company is considering making the switch from Angular 1.5.x to Angular 2. Currently, our codebase is in ES5, so we are also exploring the possibility of transitioning to either ES6 or TypeScript.

While TypeScript offers additional OOP features compared to traditional JavaScript, our existing code follows a more functional programming approach rather than utilizing OOP concepts like classes. With this in mind, we are curious about the other advantages of migrating from JS to TS when upgrading to Angular 2.

Could you provide insight into the level of OOP involved in Angular 2?

Typescript isn't just another object-oriented programming language. It's more focused on static type verification rather than strict adherence to OOP principles. This distinction can be seen when comparing Java and Smalltalk. Recently, I came across a bug in my colleague's code where he mistakenly used a `for` loop with an assumption of working with an array, but it turned out to be something else (Array.prototype.forEach is quite useful for catching such errors).

Deciding whether the effort of adding type annotations throughout your codebase is beneficial depends on individual perspectives.

In contrast, ES6/ESNext provides improved ways to write code intuitively. For instance, one might argue that

function(arr) {
  var foo = arr[0];
  var bar = arr[1];
  return foo + bar;
}

could be simplified as

([foo, bar]) => foo + bar

This convenience extends to other features, especially for those who prefer functional programming. Rather than chaining methods like

Object.keys(someObj)
  .map(k => someObj[k])
  .filter...

now you have the option of using simply `Object.values`. The language brings forth numerous enhancements facilitating cleaner and more concise code.
