Is there a specific use of init() method in javascript?
Consider
var obj = {
init: function(){
return "Hello World";
},
foo: function(){
return "Foo";
}
}
Is there a difference between obj.init() v/s obj.foo()? Is it just a naming convention? Renaming init to main() has no effect. I realize that init is a naming convention that is used to place all of the initialization code for the object. Is that correct?
init has no special meaning in Javascript. It is just an ordinary valid identifier, like foo.
It is often used instead of initialize, because most developers know that init means initialize, and it's shorter to type. If you prefer, there would be no problems with using initialize instead.
Init has no special meaning in javascript. If you're looking for a constructor, in javascript you can call a function with the new keyword. This will create a 'new' this object and pass it to that function as the scope.
function obj(){
this.foo = function() {
return "foo";
}
}
var o = new obj(); // o.foo() returns "foo"
a lot of time people will use an init function to encapsulate the constructor functionality. It is common practice to also write an init function for setting up a plain object when you're not using a constructor.
