how to use the functionsin function from lodash in javascript

To use the functionsIn function from lodash in JavaScript, follow these steps:

1. Install lodash by running the command npm install lodash in your project directory.

2. Import the functionsIn function from lodash in your JavaScript code using the following code:

index.tsx
const { functionsIn } = require('lodash');
43 chars
2 lines

3. Call the functionsIn function on an object to get an array of its own and inherited function property names. For example:

index.tsx
class MyClass {
  myMethod() {
    console.log('Hello, world!');
  }
}

class MySubclass extends MyClass {
  myOtherMethod(){
    console.log('Howdy, folks!');
  }
}

const myInstance = new MySubclass();

const functionNames = functionsIn(myInstance); 
console.log(functionNames);
// Output: ["myOtherMethod", "myMethod"]
322 chars
18 lines

In the example above, functionsIn is used to retrieve the function property names of an instance of MySubclass, which has inherited the myMethod function from its parent class MyClass. The output of the console.log statement shows an array containing both myMethod and myOtherMethod, arranged in the order they were defined.
