FILTER

Takes an array or an object as well as a lambda function or an array of values to keep. If the input is an array, it returns a new array with all the values that match the lambda function or are in the array of values to keep. If the input is an object, it returns a new object with all the key-value pairs with values that match the lambda function or are in the array of values to keep.

Syntax 

FILTER(array | object, values_to_keep | LAMBDA(item, [expr]))
