/**

* Determines whether a nested path on an object has a specific value, in
|
|
* [`R.equals`](#equals) terms. Most likely used to filter a list.

* @category Relation

|
* @typedefn Idx = String | Int | Symbol
|
|
* @sig a -> [Idx] -> {a} -> Boolean
|
|
* @param {*} val The value to compare the nested property with
|
|
* @param {Array} path The path of the nested property to use
|
|
* @param {Object} obj The object to check the nested property in
|
|
* @return {Boolean} `true` if the value equals the nested object property,
|
|
* `false` otherwise.

* @see R.whereEq, R.propEq, R.pathSatisfies, R.equals

* @example
|
|
*
|
|
* const user1 = { address: { zipCode: 90210 } };

* const user2 = { address: { zipCode: 55555 } };
