How to take particular key value pairs from json array : <p>I have a large amount of data in JSON array format.
A shorter version of which is as shown below</p>

<pre><code>[{"Item": "Item1", "Unit CP": 100, "Unit SP": 150, "Quantity": 1, "TotalSP": 150},
{"Item": "Item2", "Unit CP": 50, "Unit SP": 70, "Quantity": 7, "TotalSP": 490},
{"Item": "Item3", "Unit CP": 1000, "Unit SP": 900, "Quantity": 1, "TotalSP": 900},
{"Item": "Item4", "Unit CP": 200, "Unit SP": 500, "Quantity": 2, "TotalSP": 1000},
{"Item": "Item5", "Unit CP": 300, "Unit SP": 311, "Quantity": 3, "TotalSP": 933},
{"Item": "Item6", "Unit CP": 750, "Unit SP": 755, "Quantity": 2, "TotalSP": 1510}]
</code></pre>

<p>i want to get a JSON array of objects with keys "Item" and "Unit SP" only i.e</p>

<pre><code>[{"Item": "Item1", "Unit SP": 150},
{"Item": "Item2", "Unit SP": 70},
{"Item": "Item3", "Unit SP": 900},
{"Item": "Item4", "Unit SP": 500},
{"Item": "Item5", "Unit SP": 311},
{"Item": "Item6", "Unit SP": 755}]
</code></pre>

<p>Is there a simpler way to do so in javascript without parsing through the whole array?
Thanks in advance </p>
