A Brief Overview of JSON

JSON stands for JavaScript Object Notation. It’s the text format used for sharing data, and is the most popular data transmission format. JSON is used for local data while JSONP is used for remote data.

Here are a few other things to keep in mind about this data format:

  • JSON is language independent (it’s available in php, Python, etc)
  • JSON keys are wrapped in quotes
  • JSON keys can be any valid string
  • Special characters can make it difficult to access data, and you should use underscores instead of hyphens
  • JSON has to be parsed into JavaScript (which can be done with eval or JSON.parse – JSON.stringify does the opposite of parse)
  • A great alternative to XML
