Pronic numbers in JavaScript
A Pronic number is a number which is the product of two consecutive integers, that is, a number of the form n(n + 1).
We are required to write a JavaScript function that takes in a number and returns true if it is a Pronic number otherwise returns false
Let’s write the code for this function −
Example
const num = 90; const isPronic = num => { let nearestSqrt = Math.floor(Math.sqrt(num)) - 1; while(nearestSqrt * (nearestSqrt + 1) <= num){ if(nearestSqrt * (nearestSqrt+1) === num ){ return true; }; nearestSqrt++; }; return false; }; console.log(isPronic(num));
Output
Following is the output in the console −
true
