JavaScript: Filter out the element(s) of a given array, that have one of the specified values

JavaScript fundamental (ES6 Syntax): Exercise-30 with Solution

Filter Elements Matching Values

Write a JavaScript program to filter out the element(s) of a given array that have one of the specified values.

• Use Array.prototype.includes() to find values to exclude.
• Use Array.prototype.filter() to create an array excluding them.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
// Define a function named without that filters out specified values from an array.
const without = (arr, ...args) => arr.filter(v => !args.includes(v));

// Test the function with different arrays and values to be filtered out.
console.log(without([2, 1, 2, 3], 1, 2)); // Output: [3]
console.log(without([2, 1, 2, 3], 3));    // Output: [2, 1, 2]

Output:

[3]
[2,1,2]
