In this article we will show you the solution of create JSON array in JavaScript, let us understand JSON first. The JSON stands for JavaScript Object Notation. It is a lightweight data-exchanging format.

It is used basically with API. JSON is language-independent and supports all kinds of frameworks and languages.

Step By Step Guide On Create JSON Array In JavaScript :-

Now let us see how to create an array using JSON.

Method 1 -

Creating just one array.
   var Thomas = [ {
        " name ":" Thomas " ,
        " city ": " London " ,
        " age " : " 30 "
    },
]
    document.write("Name : "+Thomas.name+"<br>");
    document.write("city : "+Thomas.city+"<br>");
    document.write("age : "+Thomas.age+"<br>");

1. Creating a variable and all the information in the array ( ex- name, city , age…)
2. Using document.write to show the array

Method 2 -

Creating many array at once.

var array = [ {
        " name " : " Thomas " ,
        " city ": " London " ,
        " age " : " 30 "
    },
{
    " name " : " Peter " ,
        " city " : " NewYork " ,
        " age " : " 21 "
},
{
    " name " : " Mary " ,
        " city " : " LA " ,
        " age " : " 34 "
},
{
    " name ":" Leo " ,
        " city ": " chicago " ,
        " age " : " 50 "
}
]
    for(var c=0;c<3;c++){
        document.write(array[c].name + " 's name : " + array[c].name + "<br>");
        document.write(array[c].name + " 's city : " + array[c].city + "<br>");
        document.write(array[c].name + " 's age : " + array[c].age + "<br>");
    }

1. Creating many arrays, containing information (ex- name, city ,age…)
2. Here a for loop was created to write all the arrays.

Method 3 -

Representing array as a table.

var array = [ {
    " name ":" Thomas " ,
        " city ": " London " ,
        " age " : " 30 "
},
{
    " name ":" Mary " ,
        " city ": " LA " ,
        " age " : " 34 "
} ]
console.table(array);

1. Here console.table() used to represent the array as the table.

Method 4 -

Push element in array.

var array = [ {
    " name ":" Thomas " ,
        " city ": " London " ,
        " age " : " 30 "
},
{
    " name ":" Mary " ,
        " city ": " LA " ,
        " age " : " 34 "
} ]
let family2 = {
    " name ":" Leo " ,
        " city ": " chicago " ,
        " age " : " 50 "
}
array.push(family2);
console.table(array);

Conclusion :-

Lastly, in conclusion, here we can say that with the help of this article create a JSON array in JavaScript.
