Error in Appendix A - Smaller Changes - Unicode code point escapes

[ronen-e]

Where:
Line 91 in Appendix A - Other changes

// Valid in ECMAScript 5 and 6
var \u{61} = "abc";

console.log(\u{61});      // "abc"

// equivalent to:
 console.log(a);          // "abc"

Reason:
the text "Valid in ECMAScript 5 and 6" is incorrect
Code point escapes were added to JavaScript in ECMAScript 2015 (ES6).
The example is not valid for ES5

Suggested Fix:

// Valid in ECMAScript 6
var \u{61} = "abc";

console.log(\u{61});      // "abc"

// equivalent to:
 console.log(a);          // "abc"
