In JS sorting on number will behave like a string.
For eg;
a = [1,23,32,12,112,321];
a.sort();
Will Result in => [1, 112, 12, 23, 32, 321];
So for Numerical Sorting, Always use a callback function like this =>
var b = a.sort(function(x,y){
return a-b;
});
2. x= 5;
y= 'aaa'
z= x/y
look into resuly and then see typeof z
then try
z < 16
z >16
z === 16
or
z === z
3- Node.js
It runs on
v8 & Libuv
as we we know v8 is javascript engine.
Libuv supports servers side operation with javascripts which we do in server side languages eg; php, java etc.
4. xhr depricated by fetch api
so in future code avoid xhr and replace it by fetch api
Read more : about fetch
5. Heroku cloud gives free supporting upto 500 mb for website hostings.
6. event queue:-
Node runs on single thread so event queue is to used handle multiple requests
All request are store in event queue as a object
NOTE:- Always keeps your folder name in small with a hyphen if require to seperate
Sometimes create problem on the server
How? Don't know.
