How to use spread operator In Javascript
The Spread operator allows an iterable to expand in places where 0+ arguments are expected. It is mostly used in the variable array where there is more than 1 value is expected. It allows us the privilege to obtain a list of parameters from an array.
The syntax of the Spread operator is the same as the Rest parameter but it works completely opposite of it.
Syntax:
let variablename1 = [...value];
Example: We are using spread operator.
// Sample array
const numbers = [5, 2, 8, 1, 4];
// Using spread operator to find the minimum element
const minElement = Math.min(...numbers);
console.log('Minimum Element:', minElement);
// Using spread operator to find the maximum element
const maxElement = Math.max(...numbers);
console.log('Maximum Element:', maxElement);
Output
Minimum Element: 1 Maximum Element: 8
Find the min/max element of an Array using JavaScript
Finding the minimum or maximum element of an array in JavaScript involves determining the smallest or largest value from the array’s elements. This operation is crucial for various tasks, such as data analysis, optimization problems, and comparisons within algorithms.
The minimum and maximum elements in an array can be found using the following methods:
