Invalid shorthand property initializer

I wrote the following code in JavaScript for a node project, but I ran into an error while testing a module. I’m not sure what the error means. Here’s my code:
var http = require(‘http’);
// makes an http request
var makeRequest = function(message) {
var options = {
host: ‘localhost’,
port = 8080,
path : ‘/’,
method: ‘POST’
}
// make request and execute function on recieveing response
var request = http.request(options, function(response) {
response.on(‘data’, function(data) {
console.log(data);
});
});
request.write(message);
request.end();
}
module.exports = makeRequest;

When I try to run this module, it throws the following error:
$ node make_request.js
/home/pallab/Desktop/make_request.js:8
path = ‘/’,
^^^^^^^^^^

I dont quite get what this means, and what I can do to resolve this.

Solution 1:

Because its an object, the way to assign value to its properties is using :.

Change the = to : to fix the error.

var options = {
  host: 'localhost',
  port: 8080,
  path: '/',
  method: 'POST'
 }

Solution 2:

In options object you have used “=” sign to assign value to port but we have to use “:” to assign values to properties in object when using object literal to create an object i.e.”{}” ,these curly brackets. Even when you use function expression or create an object inside object you have to use “:” sign.
for e.g.:

    var rishabh = {
        class:"final year",
        roll:123,
        percent: function(marks1, marks2, marks3){
                      total = marks1 + marks2 + marks3;
                      this.percentage = total/3 }
                    };

john.percent(85,89,95);
console.log(rishabh.percentage);

here we have to use commas “,” after each property.
but you can use another style to create and initialize an object.

var john = new Object():
john.father = "raja";  //1st way to assign using dot operator
john["mother"] = "rani";// 2nd way to assign using brackets and key must be string

Solution 3:

This error usually comes when you try to assign an object with Equal to(=) sign rather than colon (:)

The correct code should be like:-

var options = {
  host: 'localhost',
  port: 8080,
  path: '/',
  method: 'POST'
 }
