Accessing a JSON attribute that is equal to a specific value in javascript [duplicate]

This question already has an answer here:

• How to find a value in a multidimensional object/array in Javascript? 5 answers

I have a JSON object array like this:

people {
 {
    name: 'Alice',
    age: '25',
 },
 { 
    name: 'Bob',
    age: '34' 
 }
} 

I want to access the 'age' value of an person which has an 'name' value of 'Alice'. How do I do this in javascript? Something like (in pseudocode of what the logic is I'm aware this is not possible in javascript):

people['age'].value where name == 'Alice'

and the result would be: '25'. There seem to be a lot of related JSON questions, but none of the ones I found (as far as I could find) addressed this particular question
