How to use the key of an object

Question

If there is:

var obj = {a: 'This is a', b: 'This is b', c: 'This is c'}
var select = 'b';

How can I make to work something like this:

console.log(obj.select); // This would output: This is b

Use bracket notation

var obj = {
  a: 'This is a',
  b: 'This is b',
  c: 'This is c'
}
var select = 'b';
console.log(obj[select]);
