JavaScript: Find all elements in a given array except for the first one
JavaScript fundamental (ES6 Syntax): Exercise-31 with Solution
All Elements Except First in Array
Write a JavaScript program to find all elements in a given array except the first one. Return the whole array if its length is 1.
- Return Array.prototype.slice(1) if Array.prototype.length is more than 1, otherwise, return the whole array.
Sample Solution:
JavaScript Code:
//#Source https://bit.ly/2neWfJ2
// Define a function named tail that returns all elements of an array except the first one.
const tail = arr => (arr.length > 1 ? arr.slice(1) : arr);
// Test the function with different input arrays.
console.log(tail([1, 2, 3])); // Output: [2, 3]
console.log(tail([1])); // Output: [1] (unchanged because the array has only one element)
Output:
[2,3] [1]
