Returns the changed fields from A -> B. It's assumed that A and B have the same shape. ie. returns an object that only consists of fields which have changed in B compared to A.
Produces a CompareChangeSet between two arrays.
Compares A to B. Assumes they are simple objects, essentially key-value pairs, where the values are primitive values or other simple objects. It also works with arrays.
Compares the keys of two objects, returning a set of those in common, and those in either A or B exclusively.
Yields numerical values based on the an input of objects and the property to use.
Returns the closest matching entry, tracing path in an array, Map or simple object.
Returns an entry with undefined value at the point where tracing stopped.
Use traceRecordEntryByPath to step through all the segments.
Returns a copy of object with integer numbers as keys instead of whatever it has.
Maps the contents of data using mapper as a structured set of map functions.
Maps the keys of an object, returning a transformed object.
const input = {
hello: `there`,
chap: `chappie`
Maps the top-level properties of an object through a map function. That is, run each of the values of an object through a function, setting the result onto the same key structure as original.
Returns a new object based on data but with all
properties prefixed by prefix.
Helper function to get a 'friendly' string representation of an array of RecordEntry.
Returns the direct children of a tree-like object as a pairing of node name and value. Supports basic objects, Maps and arrays.
Returns a human-friendly debug string for a tree-like structure
Enumerates over children of node towards the node named in path.
This is useful if you want to get the interim steps to the target node.
Merge corresponding objects from arrays a and b.
