Lodash _.pick

Overview

lodash is a widely used JavaScript library which provides a wide variety of utility functions for common programming tasks, including object manipulation. One such utility function is the _.pick method. This method is used to create a new object with properties that have been picked from an existing object.

The _.pick method takes two arguments: the first argument is the object from which properties will be picked, and the second argument is an array or list of property names to be picked from the object. The method then returns a new object containing only the properties that were specified in the second argument.

Here is an example usage of the _.pick method:

const originalObject = { name: 'John', age: 30, location: 'New York' };

const pickedObject = _.pick(originalObject, ['name', 'age']);

console.log(pickedObject);
// Output: { name: 'John', age: 30 }

In this example, we have an initial object with three properties: name, age, and location. We then call the _.pick method and pass in the original object as the first argument, and an array of property names that we want to keep as the second argument. The method then returns a new object with only the name and age properties.

The _.pick method can also be used with multiple objects, by passing in more than one object as arguments. In this case, properties are picked from the first object that contains them. If multiple objects have properties with the same name, the value from the first object is used.

The _.pick method is useful for simplifying objects by removing unnecessary properties, or creating new objects with specific properties for use in other parts of the code. It is also a useful tool for creating clean and readable code that is easy to maintain.

Overall, the lodash _.pick method provides a valuable utility function for developers working with JavaScript objects. Its ability to pick properties from an object and create a new object with only those properties makes it a commonly used method in programming projects.
