2633. Convert Object to JSON String π
Description
Given a value, return a valid JSON string of that value. The value can be a string, number, array, object, boolean, or null. The returned string should not include extra spaces. The order of keys should be the same as the order returned by Object.keys()
.
Please solve it without using the built-in JSON.stringify
method.
Example 1:
Input: object = {"y":1,"x":2} Output: {"y":1,"x":2} Explanation: Return the JSON representation. Note that the order of keys should be the same as the order returned by Object.keys().
Example 2:
Input: object = {"a":"str","b":-12,"c":true,"d":null} Output: {"a":"str","b":-12,"c":true,"d":null} Explanation: The primitives of JSON are strings, numbers, booleans, and null.
Example 3:
Input: object = {"key":{"a":1,"b":[{},null,"Hello"]}} Output: {"key":{"a":1,"b":[{},null,"Hello"]}} Explanation: Objects and arrays can include other objects and arrays.
Example 4:
Input: object = true Output: true Explanation: Primitive types are valid inputs.
Constraints:
value
is a valid JSON value1 <= JSON.stringify(object).length <= 105
maxNestingLevel <= 1000
- all strings contain only alphanumeric characters
