+/**
+* This method is like `partial` except that partially applied arguments are appended to the arguments it receives.
+*
+* The partialRight.placeholder value, which defaults to a `symbol`, may be used as a placeholder for partially applied arguments.
+*
+* Note: This method doesn't set the `length` property of partially applied functions.
+*
+* @template F The type of the function to partially apply.
+* @param func The function to partially apply arguments to.
+* @param partialArgs The arguments to be partially applied.
+* @returns Returns the new partially applied function.
+*
+* @example
+* function greet(greeting, name) {
+*   return greeting + ' ' + name;
+* }
+*
+* const greetFred = partialRight(greet, 'fred');
+* greetFred('hi');
+* // => 'hi fred'
+*
+* // Partially applied with placeholders.
+* const sayHelloTo = partialRight(greet, 'hello', partialRight.placeholder);
+* sayHelloTo('fred');
+* // => 'hello fred'
