Once you have your JSON string (Im assuming you know how to get it because if not that's a different question altogether) you can save it using this function:

function saveText(text, filename) {
   var a = document.createElement('a');
   a.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));
   a.setAttribute('download', filename);
   a.click()
}

Call it:

var obj = {
   a: "Hello",
   b: "World"
};
saveText(JSON.stringify(obj), "filename.json");

Server-side storage: On someone else’s computer (often times one that is in a data warehouse), in a database. Good for storing sensitive information.,Server-side storage Storage on the server,Come up with a few examples of when you think data would be stored server-side vs client-side.,Describe a situation where you would use localStorage instead of server-side storage.

We have an employee.json file in a directory, within the same directory we have a js file, in which we want to import the content of the json file.,Note − While the first function is better suited for node environment, the second function only works in the web environment because the fetch API is only accessible in the web environment.,After running any of the above using require or fetch function, the console output is as follows −,We can use any of the two ways to access the json file −

employees.json

"Employees": [{
      "userId": "ravjy",
      "jobTitleName": "Developer",
      "firstName": "Ran",
      "lastName": "Vijay",
      "preferredFullName": "Ran Vijay",
      "employeeCode": "H9",
      "region": "DL",
      "phoneNumber": "34567689",
      "emailAddress": "ranvijay.k.ran@gmail.com"
   },
   {
      "userId": "mrvjy",
      "jobTitleName": "Developer",
      "firstName": "Murli",
      "lastName": "Vijay",

GATE Computer Science Notes,Writing code in comment? Please use ide.geeksforgeeks.org, generate link and share the link here.,Object: It is a set of name or value pairs inserted between {} (curly braces). The keys must be strings and should be unique and multiple key and value pairs are separated by a, (comma). Syntax:  ,Note: string, number, boolean, null are simple data types or primitives data types whereas object and array are referred as complex data types. 

  1. String: JSON strings must be written in double quotes like C-language there are various special characters(Escape Characters) in JSON that you can use in strings such as \ (backslash), / (forward slash), b (backspace), n (new line), r (carriage return), t (horizontal tab) etc. 
    Example:

for Escape Character / (forward slash).
