I'm trying to search through an associative array to find a key that ends with the letter "r". When I use the "in" javascript keyword with a static string, it works fine but not when using regex dynamically.

Object.keys(obj) retrieves the keys from the object and returns them as an array. This array can then be filtered using Array.prototype.filter to extract specific keys:
filteredKeys =
Object
.keys(obj)
.filter(function (key) {
return /pattern/.test(key);
});
Loop through the object's properties and check if they match a specified expression. If there is a match, return the name of the property.
function findMatchingProperty(expression, obj)
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
if (expression.test(prop)) {
return prop;
}
}
}
return null;
}
If you need to get all matching property names:
function findAllMatchingProperties(expression, obj)
var matches = [];
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
if (expression.test(prop)) {
matches.push(prop);
}
}
}
return matches;
}
If you need a quick and dirty test, you can use this approach:
/r":/.test(JSON.stringify(data));
Additionally, zzzzBov's functional solution leveraging Array.prototype.some() can also be implemented like this:
Object.keys(data).some(function (prop) {
return /r$/.test(prop);
});
