JavaScript code to change an array into a stringified format

I have encountered a challenge with transforming an array. The original array looks like this:

   array =  [
    {
        "name": "name",
        "value": "Olá"
    },
    {
        "name": "age",
        "value": "23"
    },
    {
        "name": "isVisible",
        "value": "1"
    }
]

The goal is to convert it into the following string format:

"{\"name\":\"Olá\",\"age\":123,\"isVisible\":true}"

Despite attempting various methods, I have not been successful in achieving this. My most recent attempt was as follows:

array = array.map((p) => {
          return Object.values(p).join(':').replace(/\[/g, '{').replace(/]/g, '}').toString();
        }),

Any suggestions or solutions would be greatly appreciated.

javascript arrays json stringify

Answer №1

To easily convert an array into a JSON string, start by creating an empty object. Then loop through the array to populate the object with key-value pairs. Finally, use JSON.stringify(obj) to generate the desired result.

Here is an example:

var obj = {};
array =  [
    {
        "name": "name",
        "value": "Bonjour"
    },
    {
        "name": "age",
        "value": "30"
    },
    {
        "name": "isVisible",
        "value": "0"
    }
]

for(let item of array) {
    obj[item.name] = item.value;
}

const jsonString = JSON.stringify(obj);
console.log(jsonString);
/*
output : "{\"name\":\"Bonjour\",\"age\":123,\"isVisible\":false}"
*/
