es-toolkit/dist/compat/predicate/conformsTo.mjs

A state-of-the-art, high-performance JavaScript utility library with a small bundle size and strong type annotations.

//#region src/compat/predicate/conformsTo.ts
/**
* Checks if `object` conforms to `source` by invoking the predicate properties of `source` with the corresponding property values of `object`.
*
* Note: This method is equivalent to `conforms` when source is partially applied.
*
* @template T - The type of the target object.
* @param target The object to inspect.
* @param source The object of property predicates to conform to.
* @returns Returns `true` if `object` conforms, else `false`.
*
* @example
*
* const object = { 'a': 1, 'b': 2 };
* const source = {
*   'a': (n) => n > 0,
*   'b': (n) => n > 1
* };
*
* console.log(conformsTo(object, source)); // => true
*
* const source2 = {
*   'a': (n) => n > 1,
*   'b': (n) => n > 1
* };
*
* console.log(conformsTo(object, source2)); // => false
