Could you explain?

Question

var a=1;
document.write(a++);
document.write(++a);

Output is 13

Answer 1

a++ is post-increment, hence it print value of a (which is 1) and increment it. So now a has become 2.
++a is pre-increment so now the value of a(which is already 2) increases by 1, and a becomes 3 and then it will be printed. Since there is no next line, output you get is 13.

Answer 2

document.write(a++)
// Write a which is 1 and increment it.
document.write(++a)
// Increment a (now 3) and write it (3). There was no line break so both numbers are next to each other: 13.

Answer 3

ans : import * as

Answer 4

a++: first outputted, then incremented (to 2)
++a: first incremented (to 3), then outputted

Answer 5

there are prefix and postfix increments so by this write istead of writeline results are written near by each other.

Answer 6

This is not 13.This is 1 and 3 concat.

Answer 7

You forgot make a line break...

Answer 8

Fill in the blanks to import the following from "util/calc.js":
export const hit = (x, y, z) => {
return x * y + z / 2;
}
export const degree = 50;
import * as calc from "util/calc";
calc.hit(1, 2, calc.degree);

Answer 9

ans = import * as

Answer 10

Your question has been thoroughly answered? @Safaa
There are two outputs:
The first document.write outputs 1,
The second one outputs 3
Since there is no space, separator or line break, they are written side by side to appear as 13 when actually it should be 1 and 3.

Answer 11

calc.hit(1, 2, calc.degree);

Answer 12

The ans is not 13

Answer 13
