javascript-lodashHow can I use Lodash to create a hashmap in Javascript?

A hashmap is an efficient data structure that maps keys to values. Lodash is a JavaScript library that provides utility functions for common programming tasks. It can be used to create a hashmap in JavaScript.

Example code

const _ = require('lodash');

const myHashMap = _.zipObject(['key1', 'key2'], ['value1', 'value2']);


Output example

{ key1: 'value1', key2: 'value2' }

In the example code above:

  • require('lodash') imports the Lodash library.
  • _.zipObject takes two arrays and creates a hashmap from them. The first array contains the keys and the second array contains the corresponding values.
  • console.log(myHashMap) prints the hashmap to the console.
