Create and Read JSON file

Question

1. I created a JSON file as follows

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

}

2. 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));    

3. 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

Answer 1

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.

Answer 2

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.

Answer 3

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
