for…of iterator - the for-of iterator is similar to for loop. The for...of statement loops/iterates through the collection, and provides you the ability to modify specific items.
Nullish Operator - If the left hand side value is null or undefined this operator returns the right-hand side value otherwise left hand side value.for example: const value= null ?? “Hello”;
Spread Operator - Spread operator helps to expand the array into individual elements. So, it can be used to expand the array in a place where zero or more elements are expected.
Object.entries() - The Object.entries() method returns an array of a given object's own enumerable string-keyed property [key, value] pairs. This is the same as iterating with a for...in loop, except that a for...in loop enumerates properties in the prototype chain as well.
