how to use the has function from the underscore library in javascript

The _.has function from the Underscore library is used to determine if a specified object has the given property.

Here is an example of how to use the _.has function:

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

// Define an object
const myObj = { name: 'John', age: 30, job: 'Developer' };

// Check if the object has the 'name' property
if (_.has(myObj, 'name')) {
  console.log('The object has the property name');
} else {
  console.log("The object doesn't have the property name");
}

// Check if the object has the 'education' property
if (_.has(myObj, 'education')) {
  console.log('The object has the property education');
} else {
  console.log("The object doesn't have the property education");
}

In this example, we import the underscore library using the require function. Then, we define an object called myObj with three properties.

We use _.has function twice to check if the myObj object has the name and education properties.

If the object has the property, the function returns true, and the first console.log statement is executed. If the object does not have the property, the function returns false, and the second console.log statement is executed.

This is just one example of how to use the _.has function. You can use it in many different ways depending on your specific needs.
