Clustered index - multi-part vs single-part index and effects of inserts/deletes

help you fix your problem Yes, inserting into the middle of an existing table (or its page) could be expensive when you have a less than optimal clustered index. Worst case would be a page split : half the rows on the page would have to be moved elsewhere, and indices (including non-clustered indices on that table) need to be updated.
You can alleviate that problem by using the right clustered index - one that ideally is:

        echo "Key={$key}, Value: {$value}";

help you fix your problem If ES6 is not a problem, you can use array.prototype.findIndex and string.prototype.includes:

var search= "nana";
var index = myArray.findIndex(el => el.includes(search));
