Parsing JSON Objects

The Curly Braces

In JSON, objects are wrapped in curly braces {}. This will be our signal to dive deeper and parse the properties inside it.

The Approach

1. Slice the Braces: Remove the starting and ending curly braces.
2. Split Properties: Split the string by commas to get individual "key": "value" strings.
3. Key-Value Parsing: Use indexOf(":") to find where the key ends and the value starts, then slice the string to get both parts.
4. Recursive Parsing: We call the parse function recursively to handle nested objects.

1if (input[0] === "{") {
2    return input
3        .slice(1, -1)
4        .split(",")
5        .reduce((acc, item) => {
6            const index = item.indexOf(":");
7            const key = item.slice(0, index);
8            const value = item.slice(index + 1);
9            acc[parse(key)] = parse(value);
10            return acc;
11        }, {});
