javascript-lodashHow do I check if an array contains a value using Lodash in JavaScript?
The easiest way to check if an array contains a value using Lodash in JavaScript is to use the _.includes() method. This method takes two arguments, the array to search and the value to search for. The method returns a boolean value of true if the value is found in the array, and false if the value is not found.
Example
const array = [1, 2, 3, 4];
const value = 3;
const result = _.includes(array, value);
console.log(result); // true
This example code uses the Lodash _.includes() method to check if the array contains the value of 3. The method returns a boolean value of true, indicating that the value was found in the array.
Code explanation
const array = [1, 2, 3, 4];
: This line declares a constant variable called array and assigns it an array of values.const value = 3;
: This line declares a constant variable called value and assigns it a value of 3.const result = _.includes(array, value);
: This line uses the Lodash _.includes() method to check if the array contains the value of 3.console.log(result);
: This line logs the result of the _.includes() method to the console.
