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

The get function from the Underscore library in Javascript allows you to access properties of an object in a safe way, without throwing an error if the property does not exist. It also supports setting a default value if the property is undefined. Here is an example:

index.tsx
const obj = {
  name: 'John',
  age: 30
};
const name = _.get(obj, 'name'); // 'John'
const address = _.get(obj, 'address', 'No address provided'); // 'No address provided'

In this example, obj is an object with a name property and an age property. We can use the _.get function to safely access the values of these properties. The first argument to _.get is the object we want to access, and the second argument is the name of the property we want to access. If the property does not exist, _.get returns undefined.

In the second example, we are trying to access the address property of obj. Since obj does not have an address property, _.get will return the default value, which is 'No address provided'.

Overall, the _.get function is a convenient and safe way to access object properties in Javascript.
