Lodash is a JavaScript library that provides utility functions for common programming tasks. One of the functions that Lodash provides is _.uniq()
, which can be used to create a unique array in JavaScript.
Here is an example of how to use _.uniq()
to create a unique array:
const arr = [1, 2, 3, 1, 2, 3];
const uniqueArr = _.uniq(arr);
console.log(uniqueArr); // [1, 2, 3]
The _.uniq()
function takes an array as an argument and returns a new array with the unique values from the original array.
The code is composed of the following parts:
-
const arr = [1, 2, 3, 1, 2, 3];
: This declares a variablearr
and assigns it to an array with duplicate values. -
const uniqueArr = _.uniq(arr);
: This declares a variableuniqueArr
and assigns it to the result of calling_.uniq()
with thearr
array as an argument. -
console.log(uniqueArr);
: This logs theuniqueArr
array to the console.
