#173 JavaScript Code — Add 1 to the Array (Ex: [1, 2, 3] → [1, 2, 4])

JavaScript Code — Add 1 to the Array (like adding 1 to a number)

🧠 Example:

• [1, 2, 3] → [1, 2, 4]
• [9, 9] → [1, 0, 0]

Code:

const addFun= (arr)=>{
    for(let i=arr.length-1; i>=0; i--){
        if(arr[i]<9){
            arr[i]++;
            return arr;
        }
        arr[i]=0;
        
    }
    arr.unshift(1);
    return arr;
}

console.log(addFun([1,2,9]));
