How to Use APIkit Router in Mule 4
The APIkit Router element allows you to define an API. It helps developers generate whole code from the API specification (RAML file) itself.
Mule 4
Basic RAML API (API Manager) Design
An API provides an interface between two applications so that they can talk to each other.
Selector Expressions (update Operator)
Use selector expressions with the update operator to specify the fields to update.

Update Operator Examples
Update Operator
This operator is the one to use when you wish to change specific fields on an Object, while keeping all others the same.
pluck function in DataWeave 2.0 (mulesoft)
The pluck operator is useful for mapping the object into the array, and it returns the array of values, keys, and indexes of the object.
mapObject function in DataWeave 2.0 (mulesoft)
We use mapObject when we want to change the keys and/or values on an Object to be something else.
filterObject function in DataWeave 2.0 (mulesoft)
The filterObjectoperator iterates over a list of key-value pairs in an object and applies an expression that returns only matching objects, filtering out the rest from the output. The expression must return true or false.
Working with Objects
It processes both keys and values as a tuple.
The reduce Function In DataWeave Mule 4
Reduce function is used to do any computation while iterating on an array, so the computation result is not lost during iteration.
