peek

peek

Access deeply nested object properties using a path string.

Advantages over literal access

• The expression obj.foo.bar will throw a TypeError if obj.foo is not an object. peeking will yield undefined, instead.
• Wacky property names: obj['the question is']["'doctor who?'"] is verbose compared to peeking with the question is.'doctor who?'.

Other uses for peek

• Accessing variably-nested properties programmatically.
• Accessing the same nested property of multiple objects.

Usage

  var peek = require('peek')

  var booty = peek("lower deck.captain's quarters.secret panel.treasure")
  var pirate_ship = {
    'lower deck': {
      "captain's quarters": {
        'secret panel': {
          treasure: '5000 gold'
        }
      }
    }
  }

  console.log(booty(pirate_ship)) // == "5000 gold"

Limitations

Property names may not contain dots, as all dots are interpreted as object key separators.
