get

Gets the value of a global variable.

Methods get(key)

Purpose: This method is used to retrieve the value of a global variable stored in the Node.js global object. It allows you to access data that has been set globally from anywhere in your application.

Parameters:

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

Returns: The value of the global variable if it exists, otherwise undefined.

Usage Example:

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

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

// Retrieve and print the global variable
const appName = globalManager.get('appName');
console.log(appName); // Output: MyApp

Detailed Explanation: The get method looks up the specified key in the global object and returns its corresponding value. If the key does not exist, the method returns undefined. This method is essential for accessing global variables without needing to pass them explicitly between different parts of your application.

Notes:

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

• If you get undefined as a result, it could mean the variable was never set or it was deleted.
