pathEq (

path:Array,

val:*,

obj:Object

) : Boolean

Determines whether a nested path on an object has a specific value, in R.equals terms. Most likely used to filter a list.

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 ]

Arguments

path: Array

The path of the nested property to use

val: *

The value to compare the nested property with

obj: Object

The object to check the nested property in

Returns

Boolean

`true` if the value equals the nested object property, `false` otherwise.
