Check if Array has exact Key Value object in Javascript
arrays, javascript
Solution
In modern browsers,
testArray.some(function(o){return o["key1"] === "value2";})
will be `true` if pair is found, otherwise `false`.
This assumes each object contains only one key/value pair, and that the value is never `undefined`.
Problem
I'm doing a simple check to see if this array has an exact key value pair. for example ``` testArray = [ { "key1": "value1" }, { "key2": "value2" }, { "key1": "value2" ) ] ``` How do I check to see if the array contains the exact object { "key1" : "value2" }? Thanks for the help.
