Splitting javascript object to normal String with = sign

Question

How can I dynamically convert a json object to the following manner I do have

{ eligible: true, qualified:true }

but I need to make it like this

eligible= true, qualified=true

Is the space before the first `true` in the expected output deliberate/required? — CertainPerformance, May 28 '19 at 07:57
What have you tried to achieve this? Is the output a string? — void, May 28 '19 at 07:57
@void i am trying to achieve this to log in our splunk dashboards, which will accept in this format only — midhun k, May 28 '19 at 07:59
It's either an object, or a string/text in JSON format. There's no such thing as a "JSON object". You can use `Object.keys(myObj)` to get an array of keys., then use `.map` to create a new array. There's also `.join()`. — , May 28 '19 at 07:59
@MukeshPrajapati: yes we can use regex ,but i dont have it handy — midhun k, May 28 '19 at 07:59
Your JSON is invalid - keys need to be surrounded in `"`s, best to fix that, and then you can turn it into an object with `JSON.parse` — CertainPerformance, May 28 '19 at 08:00

You can use Object.entries to get a two dimensional array of object and then use Array.prototype.map to join the array element (key, value) with an =.

Finally join the array with a , to get the expected output.

var x = { eligible: true, qualified:true };

var newX = Object.entries(x).map(el => el.join("=")).join(", ");

console.log(newX);

If we can assume the string is a valid JSON object (yours is missing the quotes) you can parse the string as JSON and then use Object.entries to get the key value pairs which can then be mapped and joined down to your desired string output.

const jsonStr = '{ "eligible": true, "qualified":true }'
const jsonObj = JSON.parse(jsonStr)

console.log(Object.entries(jsonObj).map(e => e.join('=')).join(', '))

You can get entries of object and change the key/value to string using reduce

let obj = { eligible: true, qualified:true }


let str = Object.entries(obj).reduce((op,[key,value],index,arr)=>{
  op+= `${key}=${value}${index !== arr.length-1 ? ',' : ''} `
  return op
},'')

console.log(str.trim())
