/**
|
|
* Performs a deep comparison between a target value and a source pattern to determine if they match,
|
|
* using a custom comparison function for fine-grained control over the matching logic.
|
|
*
|
|
* This function recursively traverses both values, calling the custom compare function for each
|
|
* property/element pair. If the compare function returns a boolean, that result is used directly.
|
|
* If it returns undefined, the default matching behavior continues recursively.
|
|
*
|
|
* The matching behavior varies by data type:
|
|
* - **Objects**: Matches if all properties in the source exist in the target and match
|
|
* - **Arrays**: Matches if all elements in the source array can be found in the target array (order-independent)
|
|
* - **Maps**: Matches if all key-value pairs in the source Map exist and match in the target Map
|
|
* - **Sets**: Matches if all elements in the source Set can be found in the target Set
|
|
* - **Functions**: Matches using strict equality, or object comparison if the function has properties
|
|
* - **Primitives**: Matches using strict equality
|
|
*
|
|
* Special cases:
|
|
* - Empty objects, arrays, Maps, and Sets always match any target
|
|
* - `null` and `undefined` source values have specific matching rules
|
|
* - Circular references are handled using an internal stack to prevent infinite recursion
|
|
*
|
|
* @param {object} target - The value to be tested for matching
|
|
* @param {object} source - The pattern/template to match against
|
|
* @param {function} [compare] - Optional custom comparison function that receives:
|
|
* - `objValue` - The value from the target at the current path
|
|
* - `srcValue` - The value from the source at the current path
|
|
* - `key` - The property key or array index being compared
|
|
* - `object` - The parent object/array from the target
|
|
* - `source` - The parent object/array from the source
|
|
* - `stack` - Internal Map used for circular reference detection
|
|
* Should return `true` for a match, `false` for no match, or `undefined` to continue with default behavior
|
|
*
|
|
* @returns {boolean} `true` if the target matches the source pattern, `false` otherwise
|
|
*
|
|
* @example
|
|
* // Basic matching without custom comparator
|
|
* isMatchWith({ a: 1, b: 2 }, { a: 1 }); // true
|
|
* isMatchWith([1, 2, 3], [1, 3]); // true
|
|
*
|
|
* @example
|
|
* // Custom comparison for case-insensitive string matching
|
|
* const caseInsensitiveCompare = (objVal, srcVal) => {
|
|
* if (typeof objVal === 'string' && typeof srcVal === 'string') {
|
|
* return objVal.toLowerCase() === srcVal.toLowerCase();
|
|
* }
|
|
* return undefined; // Use default behavior for non-strings
|
|
* };
|
|
*
|
|
* isMatchWith(
|
|
* { name: 'JOHN', age: 30 },
|
|
* { name: 'john' },
|
|
* caseInsensitiveCompare
|
|
* ); // true
|
|
*
|
|
* @example
|
|
* // Custom comparison for range matching
|
|
* const rangeCompare = (objVal, srcVal, key) => {
|
|
* if (key === 'age' && typeof srcVal === 'object' && srcVal.min !== undefined) {
|
|
* return objVal >= srcVal.min && objVal <= srcVal.max;
|
|
* }
|
|
* return undefined;
|
|
* };
|
|
*
|
|
* isMatchWith(
|
|
* { name: 'John', age: 25 },
|
|
* { age: { min: 18, max: 30 } },
|
|
* rangeCompare
|
|
* ); // true
