feature request: provide op.test()

[dan-reznik]

Dear Jeff can you also make available op.test(str, regexp) to test if a particular string contains a particular regexp? (similar to the string method in js) thanks

You can use op.match(value, regexp) for this purpose. If needed, you can coerce the result to a boolean (match or no match) using !!op.match(value, regexp). Or is there a reason that match doesn't work for you?

it does work. but the reason i would use is the same we use .test() in js, efficiency over million of records. dan

OK, thanks. I'm curious: what level of performance difference do you see in that case?
