Sometimes, we want to parse JSON array with JavaScript.
In this article, we’ll look at how to parse JSON array with JavaScript.
How to parse JSON array with JavaScript?
To parse JSON array with JavaScript, we call the JSON.parse method.
For instance, we write
const myMessage = `
{
"success": true,
"counters": [
{
"counterName": "dsd",
"counterType": "sds",
"counterUnit": "sds"
},
{
"counterName": "gdg",
"counterType": "dfd",
"counterUnit": "ds"
}
]
}
`;
const jsonData = JSON.parse(myMessage);
for (const counter of jsonData.counters) {
console.log(counter.counterName);
}
to call JSON.parse with the myMessage string.
Then we loop through the parsed jsonData object’s counters array property with a for-of loop.
In it, we get the counterName property of each object with counter.counterName.
Conclusion
To parse JSON array with JavaScript, we call the JSON.parse method.
