Ans:
1.just chill,have fun (Explanation: === opearator check value and data type both so we got this result)
2.console.log(bird[“data”]); //undefined
console.log(bird[“size”]); //small
console.log(bird.size); //small
console.log(bird.data); //undefined
Explanation: data consist of string value i.e size which is not related to bird variable ,data and bird are both different variable so we got this undined value
3.console.log(sum(2,“3”)); //23
Explanation: In javascript number and string addition is return in string.
4. var numbers = [2, 4, 6, 8];
var counter = 0;
var sum = 0;
while (counter < numbers.length) {
//console.log(“No:”+numbers[counter]);//2 4 6 8
sum = sum + numbers[counter];
//console.log(“sum:”+sum);//2 6 12 20
counter++;
//console.log(“counter:”+counter);//1 2 3 4
}
console.log(sum);//20
