Is this real?
You can easily figure out which string is a real number with is-real.
$ npm install is-realconst is_real = require("is_real");
console.log(is_real(123)); // true
console.log(is_real(+123.12)); // true
console.log(is_real(-123.0)); // true
console.log(is_real("123")); // true
console.log(is_real("abc")); // false- Nothing
If there's no problem using javascript and npm, it will work well.
