Javascript Program to find the sum of elements in a given array

In this program, we need to calculate the sum of all the elements of an array. This can be solved by looping through the array and adding the value of the element in each iteration to the variable sum.

PROGRAM :

// Given Array

let array=[1,2,3,4,5,6];

// Storing length of array

let n=array.length;

let sum=0;

for(let i=0;i<n;i++){

sum=sum+array[i];

}

console.log("Sum of given array is",sum)

// Given Array let array=[1,2,3,4,5,6]; // Storing length of array let n=array.length; let sum=0; for(let i=0;i<n;i++){ sum=sum+array[i]; } console.log("Sum of given array is",sum)

OUTPUT :

Complexity

Time Complexity : O(N)
Space Complexity : O(1)
