delete

Deletes a global variable.

Methods delete(key)

Purpose: This method deletes a global variable from the Node.js global object, making it no longer accessible by its key name. It allows you to remove global variables that are no longer needed or to reset global state when necessary.

Parameters:

  • key (string): The name of the global variable you want to delete. This should match the key used when the variable was set.

Returns: true if the global variable was successfully deleted, otherwise false.

Usage Example:

const globalManager = require('global-manager');

// Set a global variable
globalManager.set('appName', 'MyApp');

// Delete the global variable
const deleted = globalManager.delete('appName');
console.log(deleted); // Output: true

// Attempt to delete a non-existent global variable
const notDeleted = globalManager.delete('nonExistentKey');
console.log(notDeleted); // Output: false

Detailed Explanation: The delete method removes the specified key and its associated value from the global object. After deletion, attempting to retrieve the variable using get will return undefined. This method is useful for managing memory and ensuring that global variables are removed when they are no longer needed, preventing potential memory leaks or unintended side effects.

Notes:

  • Ensure that the key provided matches exactly (including case sensitivity) with the key used when the variable was set.

  • Deleting essential global variables like global or process may lead to unexpected behavior and should be avoided.
