how to assign value of z = ++b without changing the value of b.

Question

var a = 3,
b = 2,
z = ++b,
z = b + a;
console.log(z);
console.log(b);

//Output: (1+2)+3 = 6
//Output: (1+2) = 3

I want to get z=b+1=3
but at the same time I want to use b later as the first given value b=2
how to do that

Answer 1

z=b+1, sets Z to 3 and doesn't increase b

Answer 2

Can we do that with arrays forexample to increase a string for many times or make loop?

Answer 4

What do you mean increase string? Considering arrays you can do a = myarr[0]+1, value of first element of myarr won't change but a will be that element +1, same thing as previous answer
