7. Increment Operator

The code below outputs the following by console.log:



  • let a = 1: a is assigned the value 1.
  • const b = ++a: a is pre-incremented (a is incremented to 2 before it is assigned to b). So, b is assigned the value 2.
  • const c = a++: a is post-incremented (a is assigned to c first with the value 2, then a is incremented to 3). So, c is assigned the value 2.
  • console.log(a): Prints the value of a, which is 2.
  • console.log(b): Prints the value of b, which is 2.
  • console.log(c): Prints the value of c, which is 1.
