javascript accessing 2d array element directly by value

Question

I have a 2d array containing data like the following:

[ 
  [ 'name', 'mike' ],
  [ 'type', 'person' ],
  [ 'age', '24' ]
]

I need to access the value of the second element of the inner array, based on the value of the first element in the inner array.

So basically I want to specify "name" and in return, receive the value "mike". How can I accomplish this without looping through the entire array?

You can't do it without looping through the array (although you can stop the loop when you find the correct value). If at all possible, you should consider using objects instead. — JJJ

why don't you use an object? { name: "mike", type: "person", age: 24 } — bbuecherl

As Juhana said, use objects:

obj = { 
  name: 'mike',
  type: 'person',
  age: 24
};

Then you can access the value of name by obj.name.
