How to recognize when to use : or = in JavaScript?
The colon (:) can be used when you want to define the property to an object while equal (=) can be used when you want to assign a value to a variable.
Example
Following is the code −
var studentDetails = { "studentId": 101, "studentName": "John", "studentSubjectName": "Javascript", "studentCountryName": "US" } console.log(studentDetails); var firstName = "David"; console.log(firstName);
To run the above program, you need to use the below command −
node fileName.js.
Here, my file name is demo325.js.
Output
This will produce the following output −
PS C:\Users\Amit\javascript-code> node demo325.js { studentId: 101, studentName: 'John', studentSubjectName: 'Javascript', studentCountryName: 'US' } David
