Data reigns supreme. However, learning to work with various data types has become increasingly crucial. Programmers, developers, and IT professionals must convert populated data structures from any language to formats other languages and systems recognize. The data exchange format that allows this is JavaScript Object Notation (JSON). JSON has grown in popularity among developers due to its lightweight, human-readable content, which requires less coding and processes faster. Click here to know more: https://www.marsdevs.com/

1. WHAT IS
WHAT IS
JSON ?
JSON ?

2. Client
Lets say there is website to display information about pizzas
And they need to talk to each other
and transfer data
Data
Server

3. Client Server
data
format?
But in what format can the data be
transferred?

4. What about plain text format?
It is easy to read for us but not easy to
interpret on the client side
The first Pizza is Neapolitan Pizza
which has a thin crust and
Mozzarella cheese, Tomatoes, Basil
Toppings
The second Pizza is New York-Style
Pizza which has a thick crust and
Mozzarella cheese, Tomatoes
toppings
how can I fetch
individual data?

5. The XML was introduced
XML has been in use for many years, still
the format could be bulky and cause
too much overhead for web services
<?xml version=”1.0” encoding=”UTF-8” ?>
<root>
<pizza>
<id>01</id>
<name>Neapolitan Pizza</name>
</pizza>
<pizza>
<id>02</id>
<name>New York-Style Pizza</name>
</pizza>
</root>
is there anything easy
to read and retrieve?

6. That is when JSON came into play
Json stands for Javascript Object Notation, a lightweight format
for storing and transporting data from a server to a web page, it
is “self-describing” and easy to understand
JSON

7. {
“name” : “value”,
“array” : [ ]
}
JSON syntax rules
Data is in name/value (anytype) pairs
Data is seperated by commas
Curly braces hold objects
Square brackets hold arrays

8. JSON looks like this
{
“pizza” : [
{
“id” : “01”,
“name” : “Neapolitan Pizza”,
“toppings” : [”Mozzarella”,”Tomatoes”,”Basil”]
}
{
“id” : “02”,
“name” : “New York-Style Pizza”,
“toppings” : [”Mozzarella”,”Tomatoes”,”Basil”]
}
]
}

9. JSON
Why is JSON preffered?
Less Verbose
Objects Align in Code
Structure Matches the Data
Faster
Readable

10. But the biggest war is
How you pronounce it?
