let fs = require("fs");

let data = fs.readFileSync(0, 'utf-8');

let idx = 0;

data = data.split('\n');

function readLine() {

idx++;

return data[idx - 1].trim();

}

//..............................................................................................................................

let noOfApplicants = parseInt(readLine()); //5

let validApplicants = 0; // This is the count variable, we assumung it to be zero now

let i = 0; // initialzation for while loop

while (i < noOfApplicants) {

let age = parseInt(readLine());

if (age > 18) {

validApplicants++

}

i++

}

console.log(validApplicants);

OR

==============================================================================================

By using continue keyword:-

let noOfApplicants = parseInt(readLine()); //5

let validApplicants = 0; // This is the count variable, we assumung it to be zero now

for (i = 0; i < noOfApplicants; i++) {

let age = parseInt(readLine());

if (age <= 18) {

continue; // if age is <= 18 skip that iteration with the help of continue keyword

}

validApplicants++;

}

console.log(validApplicants);
