Javascript - increment a var with 1 every one hundred

I want to increment a var with 1 every 100 presses. I can't write 100 else ifs for every one hundred.

    var age = 18;
    var counter = 0;

    function work() {
      counter++;
      if (counter == 100 ) {
      age++;
     } else if (counter == 200) {
      agee++;
     }
    }

You can use (counter % 100 === 0 ) condition, so whenever there is a counter which is divisible by 100 then it would return true. % operator - gives the remainder


scenario 1 : counter is between 0 - 99 then no increment in age.
scenario 2 : counter reaches 100 and age get incremented.
scenario 3 : counter is between 101 - 199 then no increment in age.
scenario 4 : counter reaches 200 and age get incremented.

var age = 18;
var counter = 200;

function work() {
  counter++;
  console.log("counter "+counter);
  if (counter% 100 === 0 ){
    age++;
  }
  console.log(age);
}
work();
counter = 399; // Just for testing purpose 
work();

console.log(age);

Use some modulus division:

var age = 18;
var counter = 0;

function work() {
  counter++;
  if (counter % 100 == 0) {
    age++;
    console.log("Age incremented to: " + age + "\nValue of counter: " + counter)
  }
}

for (var step = 0; step < 500; step++) {
  work()
}

The % symbol essentially just returns the remainder when divided by the other number (aka modulus division).

Try this:

var age = 18;
var counter = 0;

function work() {
    counter++;
    if (counter % 100 == 0) {
        age++;
    }
}
