Question

I NEED JAVASCRIPT PROGRAM

Chose an activity that you enjoy. It can be a sport that you watch or participate in, collecting, hobbies, etc. Do
not use a collection of movies since we have covered that in the assignment. Do not use the same topic as a
friend. (If two students that don’t know each other happen to select the same topic, that is fine, since they will
naturally have different property names and values.)
1. Select some aspect of the activity and create an array of objects denoting that aspect. For example, in
the case of movies, you could select movies themselves or you could select movie stars, producers,
soundtracks, etc. There are many aspects of any activity that you can use. Feel free to use the web to
research these values.
The array must contain at least 10 objects
The data must be actual data not just gibberish
Each object will have at least 4 properties with values
Each object in the array should have the same set of property names with different values
At least one string value and one number value
Other properties can be of any JavaScript value type
2. Create a function that can be used to format your object in a nice string format for output. This function
should be a pure function that takes one object as an argument and return a string. The string can be
formatted in any way that you feel is appropriate for your data. It must use one or more properties from
the object in the output string.
3. Create a new array from your array that only contains string values produced by the above function. Sort
this array alphabetically and display an appropriate heading followed by this list one string per line.
4. Prompt the user for a numeric value. Display a string (formatted using the function above) for each of the
objects that have a property (you choose) that are greater or less (up to you) the value provided by the
user. Be sure to provide a message if there are no objects that match.
5. Calculate the average value based on some property of your objects that makes sense. Output it with
descriptive text in a nicely formatted way.

// Format the objects into a string
function format(obj) {

}
//get the average runtime of the Netflix Documentaries
function avgRuntime() {

sum = sum + data[i].runtime;
}
var avg = sum / l;
console.log(

}
//Display documentaries with runtime more than the given value
function getData(val) {

}
}
var l = data.length;
var str = [];
for (var i = 0; i < l; i++) {
var st = format(data[i]);
str.push(st);
}
str.sort();
console.log("The list of top Netflix Documentaries are: ");
for (var i = 0; i < str.length; i++) {
console.log(str[i]);
}
//Prompt user for a value and display results
var val = prompt("Please enter runtime in minutes", 0);
getData(Number(val));
//Get average runtime
avgRuntime();

OUTPUT:

NOTE:

1. The above code is written in javascript with 10 data as Netflix documentaries.
2. The object has 4 properties: title,year,runtime and genre.
3. Pertaining to question number 4, it is asked that the user is prompted to enter a value, for that we are using a prompt (window prompt), to get value from the user.
4. To check the working of the above code, I recommend making an html file and enter the above code in a <script> tag. Open the html file in a browser, you will be asked to enter a value (pertaining to question 4). After entering the value, right click the page and choose "Inspect". A sidebar will be opened and click on the tab "Console". Here you can check the output of this code. The screenshot provided also shows the result using a console while inspecting the page.
