javascript-lodashHow do I use Lodash to sum up the values in an array of numbers using JavaScript?


Using Lodash, you can easily sum up the values in an array of numbers using JavaScript. The following example code uses the _.sum() method to sum up the values in an array of numbers:

const numbers = [1, 2, 3, 4, 5];
const sum = _.sum(numbers);
console.log(sum); // Output: 15

The _.sum() method takes an array of numbers as an argument and returns the sum of the values in the array. In the example above, the numbers array is passed into the _.sum() method, which returns the sum of the values in the array, 15.

Code explanation

  • const numbers = [1, 2, 3, 4, 5]; - This line of code declares a numbers constant and sets it equal to an array of numbers.
  • const sum = _.sum(numbers); - This line of code declares a sum constant and sets it equal to the result of the _.sum() method, which takes the numbers array as an argument.
  • console.log(sum); - This line of code logs the value of the sum constant to the console.
