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