JSON.parse is not a function in node js

Question

I'm new in node js and I'm trying to parse a JSON. This is what I've done so far:

const JSON = require("nodemon/lib/utils");
...
someFunction() {
let sens = [];
// sensor is the result of fs.readFileSync call and file is a json array
sens = JSON.parse(sensors);

It throws me:

JSON.parse is not a function.

How can I solve it?

why are you importing const JSON = require("nodemon/lib/utils");? — Ayush Gupta

this is was suggest me by my IDE, is it wrong? Why downvote? — CodeRonin

JSON.parse() is a standard JavaScript function supported by Node.js. You overwrite the JSON object in your first statement and this is why it doesn't work. — axiac

As an aside, don't blindly follow what your IDE tells you to do. Try to understand why it suggests something and what the consequences will be. — Federico klez Culloca

Just comment out the very first line. JSON is built in already.

//const JSON = require("nodemon/lib/utils");

Or remove it entirely, for that matter.

thanks, as I said I'm new in node so I didn't know it and nobody had my same problem in this network, so I don't know why downvote....

@GJCode Just a little tip, pretty much anything you can do in JavaScript, you can do in Node since it's built on Chrome's JavaScript engine.

JSON is kind of a global object. It doesn't need to be required. So, just remove the line where JSON is required and it'll work fine.
