/**
|
|
* Determines whether a nested path on an object has a specific value, in
|
|
* [`R.equals`](#equals) terms. Most likely used to filter a list.
|
|
*
|
|
* @func
|
|
* @memberOf R
|
|
* @since v0.7.0
|
|
* @category Relation
|
|
* @typedefn Idx = String | Int | Symbol
|
|
* @sig [Idx] -> a -> {a} -> Boolean
|
|
* @param {Array} path The path of the nested property to use
|
|
* @param {*} val The value to compare the nested property with
|
|
* @param {Object} obj The object to check the nested property in
|
|
* @return {Boolean} `true` if the value equals the nested object property,
|
|
* `false` otherwise.
|
|
* @example
|
|
*
|
|
* const user1 = { address: { zipCode: 90210 } };
|
|
* const user2 = { address: { zipCode: 55555 } };
|
|
* const user3 = { name: 'Bob' };
|
|
* const users = [ user1, user2, user3 ];
|
|
* const isFamous = R.pathEq(['address', 'zipCode'], 90210);
|
|
* R.filter(isFamous, users); //=> [ user1 ]
