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 {}
