JavaScript Classes Methods
Example
Methods can be defined in classes to perform a function and optionally return a result.
They can receive arguments from the caller.
class Something {
constructor(data) {
this.data = data
}
doSomething(text) {
return {
data: this.data,
text
}
}
}
var s = new Something({})
s.doSomething("hi") // returns: { data: {}, text: "hi" }
