I want filter out data from my data set array on basis of any like condition ?

 

Can i use reject function for that ? but how i will do this as its accepting first parameter as function.

reject(fn!isnull, {1, null, 3})

reject("*test*",local!dataset.fieldName) - Syntext might be incorrect but i want something like this
