Use a try-catch block around JSON.parse to gracefully handle invalid JSON and prevent application crashes.
Build a simple helper function that uses a try-catch block to return true or false, indicating if a string is valid JSON.
Use the third parameter of JSON.stringify to specify the number of spaces for indentation, making the output human-readable.
Pass a function as the second argument to JSON.stringify to filter out sensitive or unnecessary fields by returning undefined for specific keys.
Use the second parameter of JSON.parse as a reviver function to transform values, such as converting date strings into Date objects, during the parsing process.
Perform a deep clone by serializing an object with JSON.stringify and then immediately deserializing it with JSON.parse to create a new, independent copy.
Create a function that iterates over an object's keys, URI-encodes the keys and values, and joins them with ampersands to form a valid query string.
Generate a JSON object by programmatically combining an array of keys with a corresponding array of values using a loop.
Combine two or more objects into one using the spread operator, where properties from later objects will overwrite those from earlier ones.
Use the flatMap method to efficiently iterate over an array of objects and extract nested array data into a single, flattened array.
