Lodash is a JavaScript library that provides helpful utility functions for common tasks. One of these functions is the _.intersection()
method, which can be used to find the intersection of two arrays in JavaScript.
The _.intersection()
method takes two arrays as arguments and returns a new array containing the elements that exist in both arrays. Here is an example:
const array1 = [1, 2, 3, 4];
const array2 = [3, 4, 5, 6];
const intersection = _.intersection(array1, array2);
console.log(intersection); // [3, 4]
The _.intersection()
method will compare each element of the two arrays and will return a new array containing the elements that exist in both arrays.
Here are the parts of the example code and their explanations:
const array1 = [1, 2, 3, 4];
- This is the first array.const array2 = [3, 4, 5, 6];
- This is the second array.const intersection = _.intersection(array1, array2);
- This is where we call the_.intersection()
method with the two arrays as arguments and store the returned array in a variable.console.log(intersection);
- This is where we log the returned array to the console.
