Check for perfect square without using Math libraries - JavaScript
We are required to write a JavaScript function that takes in a number and returns a boolean based on the fact whether or not the number is a perfect square.
Examples of perfect square numbers −
4, 16, 81, 441, 256, 729, 9801
Let’s write the code for this function −
const num = 81;
const isPerfectSquare = num => {
let ind = 1;
while(ind * ind <= num){
if(ind * ind !== num){
ind++;
continue;
};
return true;
};
return false;
};
console.log(isPerfectSquare(81));
console.log(isPerfectSquare(9801));
console.log(isPerfectSquare(99));
console.log(isPerfectSquare(441));
console.log(isPerfectSquare(7648));Output
Following is the output in the console −
true true false true false
