 Template strings are a feature from a version of ECMAScript called ECMAScript 2015 (a.k.a. ECMAScript 6, ES2015, ES6, etc. - _don't ask_).
-TypeScript has the ability to rewrite code from newer versions of ECMAScript to older ones such as ECMAScript 3 or ECMAScript 5 (a.k.a. ES3 and ES5).
+TypeScript has the ability to rewrite code from newer versions of ECMAScript to older ones such as ECMAScript 3 or ECMAScript 5 (a.k.a. ES5).
 This process of moving from a newer or "higher" version of ECMAScript down to an older or "lower" one is sometimes called _downleveling_.

+By default TypeScript targets ES5, an extremely old version of ECMAScript.
 We could have chosen something a little bit more recent by using the [`target`](/tsconfig#target) option.
 Running with `--target es2015` changes TypeScript to target ECMAScript 2015, meaning code should be able to run wherever ECMAScript 2015 is supported.
 So running `tsc --target es2015 hello.ts` gives us the following output:

+When targeting an ES5-compliant engine, iterators are only allowed on values of `Array` type.
 It is an error to use `for..of` loops on non-Array values, even if these non-Array values implement the `Symbol.iterator` property.
 
 The compiler will generate a simple `for` loop for a `for..of` loop, for instance:
