This is a node package that checks if an input is a perfect square and returns true or false
npm install --save psquare
include in your script as:
var psquare = require('psquare');
Use as:
// returns true or false
// pass the number as argument to the check method
psquare.check(49);
Example would be:
var psquare = require('psquare');
// Check if a number is a perfect square or not, returns true or false
if (psquare.check(49)) {
console.log("Is perfect square")
}
