In today’s Triggre Weekend Masterclass, explore how the “list contains” function streamlines complex data structures like product quotation systems with Eddie’s expert guidance. The “list contains” function in applications is used to check if a specific item is part of a list within complex data structures. For example, in an app that handles product quotations, this function helps to filter and display only those quotations that include a selected product. It’s particularly useful in scenarios where a product might be linked to multiple entities (like quotation lines).
