The parameters used in the json.parse function in javascript may be difficult to interpret

Currently, I am examining a JavaScript file on this website. It contains the following code:

let source = fs.readFileSync("contracts.json");
let contracts = JSON.parse(source)["contracts"];

I'm curious about what exactly the JSON.parse function is doing in this snippet. Can you provide some insight?

Answer №1

When using JSON.parse in this scenario, it is converting the contents of the source file (contracts.json) into a JSON object. The code snippet

JSON.parse("contracts.json")["contracts"]
retrieves the value associated with the key contracts. To implement this, you can write the following code:

let json_obj = JSON.parse(source);
let contracts = json_obj["contracts"];
