I need to know this four-line of code what’s working 1/while loop what’s works 2/if condition what’re works 3/this array decrement what work 4/this j increment what’re works

blow the whole code

function change(x, times) {
        for(let i = 0; i < x.length; i++) {
            let j = 1; 

            //while loop what's work
            while (j <= times) {

                 //if condition what work
                if (i >= j && i < x.length-j) {

                   //this array decrement what's work
                    x[i]--; 

                }

                //this j increment what's work
                j++; 
            }

        }
        return x; 
    }

    let result = change([3, 3, 3, 3, 3, 3, 3],1)

I’m sorry. I don’t understand what you are asking about. What does this code do? What is it supposed to do? How would you like us to help?

how to perform or work this line of code


 while (j <= times) {
                 //if condition what work
                if (i >= j && i < x.length-j) {

                   //this array decrement what's work
                    x[i]--; 

                }

                //this j increment what's work
                j++; 
            }
