How to use the pairs function from underscore

Find comprehensive JavaScript underscore.pairs code examples handpicked from public code repositorys.

Underscore.pairs is a JavaScript function that converts an object into an array of key-value pairs, where each pair is represented by a two-element array containing the key and its corresponding value.

How does underscore.pairs work?

Underscore.pairs works by taking an object as its argument and returning an array of arrays where each inner array contains two elements: the key of a property in the object and its corresponding value. The function iterates over each property in the object and creates a two-element array for each key-value pair. The first element of each inner array is the key of the property and the second element is the corresponding value. The function then pushes each of these two-element arrays into a new array, which is returned as the result of the _.pairs function. Note that the order of the key-value pairs in the resulting array is not guaranteed to be the same as the order in which they were defined in the original object.

const _ = require("underscore");

const myObj = {
  name: "John",
  age: 30,
  city: "New York",
};

const pairsArray = _.pairs(myObj);

console.log(pairsArray);
// Output: [["name", "John"], ["age", 30], ["city", "New York"]]

In this example, we first import the underscore library and then define an object with some properties. We then use _.pairs to create a new array of key-value pairs, where each inner array contains a key-value pair from the original object. The resulting array is [['name', 'John'], ['age', 30], ['city', 'New York']]. Note that the order of the pairs in the resulting array is not guaranteed to be the same as the order in which they were defined in the original object.
