Question


Let’s say the following is our object −

var apiJSONObject =
[
   {subjectName:"MySQL"},
   {subjectName:"Java"},
   {subjectName:"JavaScript"},
   {subjectName:"MongoDB"}
]

Let’s check for existence of a value “JavaScript” −

Example

var apiJSONObject =
[
   {subjectName:"MySQL"},
   {subjectName:"Java"},
   {subjectName:"JavaScript"},
   {subjectName:"MongoDB"}
]
for(var i=0;i<apiJSONObject.length;i++){
   if(apiJSONObject[i].subjectName=="JavaScript"){
      console.log("The search found in JSON Object");
      break;
   }
}

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo117.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo117.js
The search found in JSON Object
