JavaScript: Get the month name from a particular date

JavaScript Datetime: Exercise-4 with Solution

Month Name from Date

Write a JavaScript function to get the month name from a particular date.

Test Data:
console.log(month_name(new Date("10/11/2009")));
console.log(month_name(new Date("11/13/2014")));
Output :
"October"
"November"

Sample Solution:

JavaScript Code:

// Define a JavaScript function called month_name with parameter dt
var month_name = function(dt){
  // Define an array containing names of months
  mlist = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];
  // Return the name of the month corresponding to the month index of the provided date
  return mlist[dt.getMonth()];
};

// Output the name of the month for the provided date "10/11/2009"
console.log(month_name(new Date("10/11/2009")));
// Output the name of the month for the provided date "11/13/2014"
console.log(month_name(new Date("11/13/2014")));

Output:

October
November

Explanation:

In the exercise above -

• The code defines a JavaScript function named "month_name()" with a parameter 'dt', representing a date object.
• Inside the function:
• It initializes an array 'mlist' containing the names of months from January to December.
• The function returns the name of the month corresponding to the month index of the provided date. It uses the "getMonth()" method of the 'Date' object, which returns the month as a zero-based index (0 for January, 1 for February, and so on).
• Console.log() outputs the month name for the provided date to the console.
