Nearly everything (excluding some primitive values) in JavaScript is an object, and can therefore have methods and accessible data. Objects are not instantiated from classes, however. They are cloned from other objects. Rather than writing a class, you would simply create a prototype object. New...
“It does block, but it’s limited in how long it can block for,” Claymore told us. Most JavaScript developers won’t use either of these options directly, Palmer pointed out: “It’s very hard to write threaded code.” But mutex libraries would likely rely on it, as might tools ...
