Yes, JavaScript will convert strings into numbers
console.log(5*"12");
60
console.log(5*"0x0C");
60 console.log(5*"12");
60
console.log(5*"0x0C");
60We use Java at the backend and of course Javascript for frontend. When serializing, in Java we should
String dataRaw = "42";
int objectId = Integer.parseInt(dataRaw);
dataRaw = "42";
var objectid = +dataRaw;PHP doesn't have that concept in it.
I always understood that the 'isNaN()' function was required to check if a numeric variable is equal to 'NaN' directly, since normal equality cannot be used as there are multiple valid bitwise representations of 'NaN' in the standard - it is a float with an exponent of all ones and a non-zero fraction. However, 'isNaN()' now seems to have been co-opted into being used to check if a string is not a number, i.e. does not represent a numeric value, and in fact I believe this is now the documented description of the function in ECMAScript?
