Create and Read JSON file

Question

I created a JSON file as follows

{
    
"fooditems" : [
        {
            "name": "pizza",
        "type": "fastfood",
        "price": 10
        },
        {
            "name": "apple",
        "type": "fruit",
        "price": 1
        }
    ]

}

created a JS file to read the JSON file

const data = require("./data.json");
    
data1 = JSON.parse(data);

data1.foodData.forEach( foodItem => console.log(foodItem));

When I run the JS, I get error for the json file

Syntax error: Unexpected token o in json at position 1 at JSON.parse

log the contents of `data` to the console before you try to parse it and check what it really looks like. Usually this error is because the data is in fact already an object (rather than a string), and therefore doesn't need parsing. `require` already treats it as an object. — ADyson, Sep 24 '20 at 21:22

You don't need to parse data since it's already and object. The following should work.

const data = require("./data.json");
data.fooditems.forEach( foodItem => console.log(foodItem));

Note foodData was change to fooditems based on the contents of the data.json file.

Your initial data JSON contains "fooditems", but in the JS file you are trying to process the "foodData". Change the "foodData" to "fooditems" and it should work.

I think that you are trying to access invalid object key in your JS file on the last line.

Instead of data1.foodData put data1.fooditems
