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

The omit function from the Underscore.js library allows you to create a copy of an object with any number of specified properties omitted. The syntax for the function is as follows:

index.tsx
_.omit(object, *keys)
22 chars
2 lines
  • object is the source object that you want to clone and omit properties from.
  • keys is one or more strings representing the keys of the object properties that you want to omit.

Here's an example of how to use the omit function:

index.tsx
const person = {
  name: 'John',
  age: 30,
  address: '123 Main St',
  phoneNumber: '555-555-5555'
};

const updatedPerson = _.omit(person, 'address', 'phoneNumber');

console.log(updatedPerson);
// Output: { name: 'John', age: 30 }
234 chars
12 lines

In the code above, we created a person object with four properties. We used the omit function to create a new object called updatedPerson with the address and phoneNumber properties omitted. Finally, we logged the updatedPerson object to the console.

Using the omit function is an easy and efficient way to create a copy of an object with specific properties omitted, which can be useful in a variety of functional programming scenarios.
