Sarfaraz I'd recommend reading the https://github.com/purescript/documentation/blob/master/language/Records.md#extending-records
or

Perhaps you are new to functional programming? Lists are supposed to be immutable, i. e. you don't change an existing list but rather construct a new one, say with
consI
