Clearing a Dictionary using Javascript

We'll implement a clear() function that simply clears the contents of the container. For example, 

Example

clear() {    this.container = {} }

You can test this using − 

Example

const myMap = new MyMap(); myMap.put("key1", "value1"); myMap.put("key2", "value2");   myMap.display(); myMap.clear(); myMap.display();

Output

This will give the output −

{ key1: 'value1', key2: 'value2' }

You can use the clear method in the same way in ES6 maps as well. For example,

Example

const myMap = new Map([    ["key1", "value1"],    ["key2", "value2"] ]); console.log(myMap) myMap.clear(); console.log(myMap)

Output

This will give the output −

Map { 'key1' => 'value1', 'key2' => 'value2' } Map {}
