remove array element with non numeric key
<p>I have an array of objects where the key is an md5 string and the value is an object
[0315778255cca8d2f773642ad1d3678f] = {a:12,b:34}. I need to remove array elements based on their key, i tried splice but failed cause i suppose the keys are non numeric. 
I also tried to splice by position, but that failed to, and even delete the element but we all know that it is not ideal.</p>

<p>I could change my implemantation from array to object but that too will have the same problems more or less i suppose.</p>

<p>Any ideas are welcome</p>
