Underscore.js is a library used to manipulate arrays and objects in JavaScript. With the pick() method, we can filter the properties of an object and return only some specified ones.
_.pick(object, *property)
object: This is the object whose properties we want to filter.*property: This is a property we want to return. It can be one or more.This function returns an object with only some properties specified.
// require underscoreconst _ = require("underscore")// create some objectslet obj1 = {one: 1, two: 2, three: 3, four: 4}let obj2 = {name: "nodejs", package: "underscore", tag: "_"}let obj3 = {a: "Apple", b: "Banana"}let obj4 = {M: "Monday", T: "Tuesday", W: "Wednesday"}// pick or select some propertiesconsole.log(_.pick(obj1, "one"))console.log(_.pick(obj2, "package", "tag"))console.log(_.pick(obj3, "a", "b"))console.log(_.pick(obj4, "T", "M"))
underscore package. obj1, obj2, obj3, and obj4. We give them some properties and values.pick() method to filter "one" property of the object obj1 and log the result to the console.pick() method to select the properties, "package" and "tag", of obj2 and print the result to the console.pick() method to filter the properties, "a" and "b", of obj4 and print the result to the console."T" and "M", of obj4 and log the result to the console.
