Input year and find in which century it falls without using slice() in JavaScript

Problem

We are required to write a JavaScript function that takes in a number that represents a year and find the century that year falls in.

For instance,

1864 falls in the 19th century.

2021 falls in the 21st century.

Example

Following is the code −

 Live Demo

const year = 1956;
const findCentury = (year) => {
   let century = 0;
   for(let i = 0; i < year; i++){
      if(i % 100 === 0){
         century++;
      };
   };
   return century;
};
console.log(findCentury(year));

Output

Following is the console output −

20
