Smart Map

This class is a mix between arrays and maps It extends maps by making it easier to retrieve keys and values, and to browse like an array with map/each/find/filter.

Path

This class is an array that works like a json path, allowing you to quickly retrieve its string version. Ex : The ar ray ['object', 'array', 0, 'otherProperty'] will be equivalent to object.array[0].otherProperty

Types

type NotEvaluable = null | undefined;
type ValueKey = string | number
type ValuePrimitive = ValueKey | boolean | symbol
type ValueFunction = Function;
type ValueDate = Date;
type ValueArray = AnyValue[];
type GenericValueArray<T> = T[];
type ValueRecord = {
    [key: ValueKey]: AnyValue;
};
type GenericValueRecord<T> = {
    [key: ValueKey]: T;
};
type ValueTree = ValueArray | ValueRecord;
type GenericValueTree<T> = GenericValueArray<T> | GenericValueRecord<T>;
type Evaluable = ValuePrimitive | ValueFunction | ValueTree | ValueDate | object;
type AnyValue = Evaluable | NotEvaluable;

type ValueRecordKeys<T, V> = { [K in keyof T]: V };
