 Check if all elements in an array are equal.
 
 Use `Array.prototype.every()` to check if all the elements of the array are the same as the first one.
+Elements in the array are compared using the strict comparison operator, which does not account for `NaN` self-inequality.

 const allEqual = arr => arr.every(val => val === arr[0]);

+### deepGet
+
+Returns the target value in a nested JSON object, based on the `keys` array.
+
+Compare the keys you want in the nested JSON object as an `Array`.
+Use `Array.prototype.reduce()` to get value from nested JSON object one by one. 
+If the key exists in object, return target value, otherwise, return `null`.
+
+```js
+const deepGet = (obj, keys) => keys.reduce((xs, x) => (xs && xs[x] ? xs[x] : null), obj);
