javascript-lodashHow do I use Lodash to create a dictionary in JavaScript?


Using Lodash, you can create a dictionary in JavaScript by using the _.fromPairs() method. This method takes an array of key-value pairs and creates an object from them.

For example:

const pairs = [
  ['name', 'John'],
  ['age', 25],
  ['location', 'New York']
];

const dictionary = _.fromPairs(pairs);

console.log(dictionary);

Output example

{ name: 'John', age: 25, location: 'New York' }

The code above creates a dictionary from an array of key-value pairs. The pairs variable is an array of arrays, each containing a key and a value. The _.fromPairs() method takes this array and creates an object from it. The resulting object is assigned to the dictionary variable, which is then logged to the console.

The following list contains the parts of the code and their explanations:

  • const pairs = [ ... ]: This declares a constant variable pairs and assigns it an array of arrays, each containing a key and a value.
  • const dictionary = _.fromPairs(pairs): This declares a constant variable dictionary and assigns it the result of calling the _.fromPairs() method with the pairs array as an argument. This creates an object from the array of key-value pairs.
  • console.log(dictionary): This logs the dictionary object to the console.
