Server was running fine until this point but server crashes when I add mock data

I was able to follow allong the videos until now but as soon as I import the mock data as below : var todos = require('../../mock/todos.json'); the server crashes and throws this error :

[nodemon] starting node src/app.js module.js:433 throw err; ^

SyntaxError: /Users/dipeshgautam/Sites/meanproject/mean-todo/mock/todos.json: Unexpected token / at Object.parse (native) at Object.Module._extensions..json (module.js:430:27) at Module.load (module.js:357:32) at Function.Module._load (module.js:314:12) at Module.require (module.js:367:17) at require (internal/module.js:16:19) at Object.<anonymous> (/Users/dipeshgautam/Sites/meanproject/mean-todo/src/api/index.js:8:13) at Module._compile (module.js:413:34) at Object.Module._extensions..js (module.js:422:10) at Module.load (module.js:357:32) [nodemon] app crashed - waiting for file changes before starting...

I checked the relative path for the todos.json file, path seems to be right. If I comment out this line : //var todos = require('../../mock/todos.json');

the server starts running again. What did I do wrong ? Please help I am not able to move forward

It sounds like there's a syntax error in the json fiile. Please post it so we can take a look.

//creating mock data
[
    {"name": "Learn JS"},
    {"name": "GO Run 2 miles"},
    {"name": "water plants"},
    {"name": "eat"},
    {"name": "watch TV"},
    {"name": "sleep"}
]

Its very fraustating . I also tried with other json files but I cannot move forward because I cannot import any .json files

you cannot make a get request for files that are not being served, the express server is set up to serve from "public" so you have to put the mock folder in the public folder and change the path in index.js accordingly, I think this was an uncaught glitch in the course
