As a programmer, I often work with data structures defined as Javascript objects. When it comes to sending these objects over a network, my go-to method is using JSON.stringify(). However, I wonder if this practice holds up in all cases.
Are there any instances where using JSON.stringify() may not work as expected, such as when dealing with static methods?
Sending only data instead of functions ensures smooth operation. JSON strictly handles values and does not support functions. For browsers that are outdated (prior to IE8), the JSON object may not be available, requiring a fallback mechanism to be implemented (some frameworks like jQuery incorporate this automatically).
JSON is essentially a subset of JavaScript, making it perfectly compatible from that perspective.
One key purpose of JSON is to easily convert data into JavaScript for manipulation, and then back again for transmission or storage.
Converting objects into JSON is actually part of its intended functionality, eliminating the need to manually write JSON code.
It's important to note that JSON has limitations - no functions or circular references are allowed, only strings, numbers, and boolean values within nested objects and arrays.
If your data is already structured in this format, you're good to go.
Unfortunately, Internet Explorer versions 6 and 7 lack native support for JSON.
However, Douglas Crockford's json2.js file serves as the foundation for all native implementations of JSON.
If !window.JSON, simply load that file to enable JSON support even in older IE browsers.
