how to use the runincontext function from lodash in javascript

To use the runInContext function from lodash in Javascript, first we must install lodash package. We can do that by running the following command in our terminal.

index.tsx
npm install lodash

Once we have installed lodash, we can import it in our Javascript file and create a new context using the runInContext function. The runInContext function takes two parameters; the first is a sandboxed context for executing code inside, and the second is an optional lodash instance to use.

index.tsx
// Import lodash library
const _ = require('lodash');

// Define context object
const context = {
  message: 'Hello World!',
  name: 'John',
};

// Create new context
const contextObj = _.runInContext(context);

// Execute code in new context
console.log(contextObj.message); // Output: Hello World!
console.log(contextObj.name); // Output: John

In the above example, we have defined a context object with two properties: message and name. We then pass this object to the runInContext function to create a new context object. Finally, we can access the properties of this new context object just like we would with any other Javascript object.

Note that the runInContext function creates a sandboxed environment for executing code, which means it does not have access to the global variables of the current scope.
