how to delete an object from a hash table in javascript

To delete an object from a hash table in JavaScript, we can use the delete operator. The delete operator removes a property from an object and returns true if the property exists, otherwise returns false.

Here's an example code snippet that demonstrates how to delete an object from a hash table in JavaScript:

index.tsx
// create a hash table
const hashTable = {
  key1: 'value1',
  key2: 'value2',
  key3: 'value3'
};

// delete an object from the hash table
delete hashTable['key2'];

// check if the object has been successfully deleted
if (hashTable['key2'] === undefined) {
  console.log('Object successfully deleted!');
} else {
  console.log('Object deletion failed!');
}

In this example, we create a hash table with three key-value pairs. Then, we use the delete operator to remove the object with key key2 from the hash table. Finally, we check if the object has been successfully deleted by verifying that its value is undefined.

Note that the delete operator only deletes the property and does not affect the length of the hash table.
