What is the main issue when using JSON.stringify(object1) = JSON. And though it's possible to compare strings containing JSON, string comparison is sensitive to differences in representation, rather than content. Hopefully, my post has helped you understand the specifics of checking objects in JavaScript. When the compared objects have a lot of properties or the structure of the objects is determined during runtime, a better approach is to use shallow check.įinally, if the compared objects have nested objects, the deep equality check is the way to go. Property names must be double-quoted strings trailing commas are forbidden. It is based upon JavaScript syntax but is distinct from it: some JavaScript is not JSON. While this check requires writing by hand the properties to compare, I find this approach convenient because of its simplicity. JSON is a syntax for serializing objects, arrays, numbers, strings, booleans, and null. isEqual (JSON.parse (a), JSON.parse (b)) // would return true is all the key-val pairs are same else false Rohit Mukherjee System Engineer at Tata Consultancy Services (company) (2018present) Author has 61 answers and 110. add this library to the include field in ).

The manual equality check requires a manual comparison of properties' values. Let a and b be the two JSON objects that you wanna compare. If you need the compatibility with older browsers, please configure the compiler in your project (e.g. The referential equality (using =, = or Object.is()) determines whether the operands are the same object instance.

JSON supports only strings, numbers, arrays, Booleans, and objects.
