Why doesn't JavaScript convert a string to an Object? [duplicate]

Question

I'm attempting to run a list of strings through an object. When I do it individually it works, but when I pass it through as a string it doesn't work. How would I fix this?

// this doesn't work
var a = "IntegrationItem1";
var data = faq.a; 

// but this works
var data = faq.IntegrationItem1;

What's causing the first example to not work? Is the variable data seeing it as faq."IntegrationItem1" instead of faq.IntegrationItem1?

var data = faq[a];

You can access properties of the object using it's names:

var a = "IntegrationItem1";
var data = faq[a];

what you need is faq["IntegrationItem1"] => faq[a]
