JSON is simple text that programs use to pass data to each other. It has a key and a value.
[ ], and a pair with { }.{"city":"Baku"} is one pair. The key is city, the value is Baku. If a comma is missing, the program rejects the text. JSON does not draw the page. It only carries the data.
JSON (JavaScript Object Notation) is a simple text format used by programs to exchange data. It relies on key-value pairs, where text is enclosed in quotes and numbers remain unquoted. Data is grouped using curly braces { }, while lists are represented by square brackets [ ]. This structure allows different systems to communicate effectively by sharing information in a standardized, machine-readable text format.
Developers use JSON when they need to transmit data between a server and a web application. For instance, weather updates or exchange rate data are frequently delivered in this format. JSON does not handle page styling or layout; its sole purpose is to carry data. Because the format is strict, missing a single comma will cause the program to reject the entire data set.
The primary purpose of JSON is to facilitate data exchange between programs. It provides a lightweight way to transmit structured information that both servers and clients can easily parse.
JSON syntax is strict because programs require precise formatting to interpret data correctly. If a comma or bracket is missing, the parser cannot read the structure, leading to an error.
No, JSON does not control the visual appearance of a page. It is strictly a data-carrying format. Styling and layout are handled by other technologies like HTML and CSS.
