In my code one of the promise returning the result like this
[{"success":true,"fileName":"./tmp/test.txt"}]
and I want to convert it into Json. how to convert it?
output:-{"success":true,"fileName":"./tmp/test.txt"}
You receive an array containing one object.
Just access array's first element, like :
var array = [{"success":true,"fileName":"./tmp/test.txt"}];
var fileName = array[0].fileName;

I'm trying to extract a value with a specified key. below are the data example;
example = [{'a':0,'b':2,'c':4}]
"results I want : 2"
To get the value of b, you would need to use example[0]['b']. You need the [0] since you also have an array enclosing the object.

How to get all key in JSON object (javascript)

I have a varible, if I print it out, I see this output:
Well, if I'd know the number '118', it would be easy, but in the program where I am using it, I don't know it. So is there any mode to get it without knowing that value?
You could use the Object.keys function to retrieve all keys of your object.
The Object.keys returns an array, you can then access the first element of that array like any other array.
const JSONString = '{"118": {"input1": 6, "input2": 1, "input3": 3}}';
const json = JSON.parse(JSONString);
const keys = Object.keys(json);
console.log(keys[0]);

Assume that i have this json obj:
var person=[{"name":"joe","age":21,"class":"a"},{"name":"moe","age":22,"class":"b"}];
i want to get the age of joe using given name which is joe.
is there something like this:
var age = person.name['joe'].age
You can use Array.prototype.find to search for a specific property in an array of objects.
var person=[{"name":"joe","age":21,"class":"a"},{"name":"moe","age":22,"class":"b"}];
const joe = person.find(item => item.name === 'joe');
if(joe)
console.log(`Joe is ${joe.age} years old`);

Say I have an array like:
var someArray = [{"id":1,"mid":"477","mname":"StackOverflow","image":"images/merchants/so.jpg"}, {"id":2,"mid":"478","mname":"Meta","image":"images/merchants/mt.jpg"}]
How do I get say the image string images/merchants/so.jpg for example?
someArray[0].image
or
someArray[0]['image']
