Given an array and the is task to find the OR and AND operations of the values of an Array using JavaScript

These are the following methods:

Approach 1: Using simple for loop

It uses a simple method to access the array elements by an index number and use the loop to find the OR and AND of values of an Array using JavaScript. 

Example 1: This example uses a simple method to find the OR of Array elements using JavaScript. 

Javascript




function OR(input) {
    if (toString.call(input) !== "[object Array]")
        return false;
 
    let total = Number(input[0]);
    for (let i = 1; i < input.length; i++) {
        if (isNaN(input[i])) {
            continue;
        }
 
        total |= Number(input[i]);
    }
    return total;
}
 
console.log(OR([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]));


Output

15

Example 2: This example uses a simple method to find the AND of Array elements using JavaScript. 

Javascript




function AND(input) {
    if (toString.call(input) !== "[object Array]")
        return false;
 
    let total = Number(input[0]);
    for (let i = 1; i < input.length; i++) {
        if (isNaN(input[i])) {
            continue;
        }
 
        total &= Number(input[i]);
    }
    return total;
}
 
console.log(AND([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]));


Output

0

Approach 2: Using reduce() method

The array reduce() method in JavaScript is used to reduce the array to a single value and executes a provided function for each value of the array (from left-to-right) and the return value of the function is stored in an accumulator. 

Syntax:

array.reduce( function( total, currentValue, currentIndex, arr ), initialValue )

Example 1: This example uses the array reduce() method to find the OR of values of an Array using JavaScript. 

Javascript




let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];
 
function ORofArray(OR, num) {
    return OR | num;
}
 
console.log(arr.reduce(ORofArray));


Output

15

Example 2: This example uses the array reduce() method to find the AND of values of an Array using JavaScript. 

Javascript




let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];
 
function ANDofArray(AND, num) {
    return AND & num;
}
 
console.log(arr.reduce(ANDofArray));


Output

0
