[izawad]

hi friends;
i am newbie in java script and i make a school app i want to use for data base like mango and fire base. how can i use? and what is the differences both.
secondly how can i make a spinner loader when user validation or registration form will fill then show spinner and get my app.
thanks to all advance.

1) Mango is the fruit. The database is MongoDB. how to use the database depends on the used library as JavaScript (the core language) cannot work with external resources. as a general note, databases are not accessible in the browser. when working in a Node.js environment, kindly refer to the instructions given by your chosen database library (use npm to find a suitable one).

i am so sorry to my Mango :)
i have read about Node js and what is system of parts of node and mongo work together in a mechanism?
or
what is the mechanism of mongo? plz help me i have made node js environment.

[Dormilich]

what is the mechanism of mongo?

want to understand how document-based databases work? the MongoDB docs will help you.

for the more likely question how to use MongoDB, I have already told you, that you need a library to interact with MongoDB. and how to work with that library is written in their documentation.

for general JavaScript documentation, MDN has proven worth.

don’t know. I don’t use any.

is java script document-based databases?

that’s a joke, right?

i can not understand what is your mean( you need a library to interact with MongoDB)?

start reading some tutorials. google is your friend.

if you’re hoping that anyone here will write your app for you then you’re wrong.

hi Dormilich,
thanks for guide of mongo db. i have read about mongo db online by mongodb.org. i make a data base sheet there r some problem but i will cover soon.
i have some confusion my app.
1= A simple calculator java script app has any data?
2= what is differentiation in a native app and a web page?
3= if i make a simple android app that consist of date making. that can i use there any data base or not?
please tell me where i have use data base or not in app making.

[Dormilich]

1 - yes
2 - a native app uses the device’s OS. a wep page uses the browser as "OS"
3 - depends on where the database is located. If it’s supposed to be on the device, you can only use the databases the device’s OS supports.
