JavaScript object has key with specific regex pattern

How to find whether a JavaScript object has key with specific regex pattern ? For example, in the below object, how to find whether it contains a key containing the word "Address"?

var obj = {Address_Line1 : "XXX", Address_Line2 :"YYY", Name : "ZZZ"};

Sure - you can do this with Array.prototype.some and Object.keys, like so:

var obj = {Address_Line1 : "XXX", Address_Line2 :"YYY", Name : "ZZZ"};

var hasKeyRegex = Object.keys(obj).some(function(key) {
  return /Address/.test(key);
});

console.log(hasKeyRegex);

hasKeyRegex will be true if the object has a key containing Address, and false if not.
