Null-safe property access (and conditional assignment) in ES6/2015

Question

Is there a null-safe property access (null propagation / existence) operator in ES6 (ES2015/JavaScript.next/Harmony) like ?. in

Answer 1

A safe deep get method seems like a natural fit for underscore.js but there the issue is avoiding string programming. Modifying @Felipe's answer to avoid string programming (or at least pushes edge cases back to the caller):

function safeGet(obj, props) {
   return (props.length==1) ? obj[keys[0]] :safeGet(obj[props[0]], props.slice(1))
}

Example:

var test = { 
  a: { 
    b: 'b property value',
    c: { }
  } 
}
safeGet(test, ['a', 'b']) 
safeGet(test, "a.b".split('.'))
