Back to 2004

When Mark was in his college times in Harvard, he wrote a program called CourseMatch, which allowed users to make class selection decisions based on the choices of other students and help them for study groups. In Feb 2004 Zuckerberg finished writing code for his new website and launched “Thefacebook.com” with the partnership with his 4 roommates.

0. Zuckerberg chooses his mates

Zuckerberg chooses his roommates with whom he wanted to work.

let friends = ["Eeduardo", "Dustin", "Andrew", "Chris"];

Mark Zuckerberg - “Chalo bhailog Facebook banate h 🤠chai pete pete ☕”

1. Adding features in Facebook ~ push() ~

As he launched Facebook, the site went up over a weekend, everyone was curious and using Facebook in the society. Mark observes and finds that there are only a number of features in Facebook. So, he uses push() function to add the features.

let features = ["Post - add to profile", "Like - to give thumbs up", "Comment - add a comment", "Share - share the post","Rate - rate the post"]
feature.push("Reactions-Angry,WoW,Love,Haha", "Save post - to save", "Edit post - make changes","Repost - add to timeline")
console.log(features);
/*[
  'Post - add to profile',
  'Like - to give thumbs up',
  'Comment - add a comment',
  'Share - share the post',
  'Rate - rate the post',
  'Reactions-Angry,WoW,Love,Haha',
  'Save post - to save',
  'Edit post - make changes',
  'Repost - add to timeline'
]*/

Mark Zuckerberg - “Chalo aab sab post mei like,commet,share aur reaction de payenge🥱”

2. Elimination of Ineffective features ~ pop() ~

Mark noticed some similar and ineffective features in the Facebook so he decided to remove the with the help of pop function to remove the element from last.

features.pop(;
console.loge(features);
/*[
  'Post',
  'Like',
  'Comment',
  'Share',
  'Reastions-Angry,WoW,Love,Haha',
  'Save post',
  'Edit post'
]*/

Mark Zuckerberg: “Share karu ya repost karu ek hi toh baat h… lo kardiya remove 😎☕”

3. Adding the Friends before the general website visitor ~ unshift() ~

For giving friends control over the site and making them different from the regular site visitors, Mark uses unshift function to complete the task.

let admin = ["Mark Zuckerberg"];
admin.unshift("Eeduardo", "Dustin", "Andrew", "Chris");
console.log(admin);
/*[ 'Eeduardo', 'Dustin', 'Andrew', 'Chris', 'Mark Zuckerberg' ]*/

Mark Zuckerberg: “Aajao bhailog ☕ ke sath kam karte h”

4. One friend gets busy ~ shift() ~

And suddenly Eeduardo gets call from his girlfriend and now he has to go for date. In this case shift function is used by Mark to remove the first element(friend).

admin.shift();
console.log(admin);
/*[ 'Dustin', 'Andrew', 'Chris', 'Mark Zuckerberg' ]*/

Mark Zuckerberg: “Ladki ka chakkar babu bhaiya ladki ka chakkar💀”

5. Giving the friends titles ~ map() ~

As they were the creators of Facebook, Mark decided to give his friends a common title ‘FB’ using map function.

let friendstitle = friends.map(friends => `FB. ${friends}`);
console.log(friendstitle);
/*[ 'FB. Eeduardo', 'FB. Dustin', 'FB. Andrew', 'FB. Chris' ]*/

Mark Zuckerberg: “Aab lag rha h \COOL* 😏”*

6. Removing features which were not so required ~ filter() ~

Mark reviewed the site and found some specific feature which is not so required, so he removed the specific feature using filter function.

let usefulfeatures = features.filter(features => !features.includes("rate the post"));
console.log(usefulfeatures);
/*[
  'Post - to add in profile',
  'Like - to give thumbs up',
  'Comment - add a comment',
  'Share - share in timeline',
  'Reactions-Angry,WoW,Love,Haha',
  'Save post',
  'Edit post'
]*/

Mark Zuckerberg: “Agar pasand h toh like/comment/share kro. Rate kyu karuu🫤isiliye ‘rate’ filter”

7. Most used feature ~ find() ~

Zuckerberg wanted to know the most used feature of their site. So, to find the most used feature, Andrew suggested Zuckerberg to use find function which helped them to find the feature having like in it.

let goodfeatures = features.find(features=> !features.includes("like"));
console.log(goodfeatures);
/*Like - to give thumbs up*/

Mark Zuckerberg: “ karo karo thumbs up 👍 karte raho “

8. Checking most important feature ~ some() ~

Mark Zuckerberg asks, “do we really have a most important feature in our website?”. Dustin, his friend uses some function to find out.

let = impfeature = features.some(features => features.includes("post"));
console.log(impfeature);
/*true

Mark Zuckerberg: “Agar kuch post hi nhi hua toh site kaise chalega? 🤡 That’s why we have POST”

9. Calculating score of features ~ reduce() ~

Mark makes a decision to give score to the feature whenever it is used. He calculates the score using reduce function.

let featureScore = [10, 6, 8, 5, 7, 9, 7];

let averageScore = featuresScore.reduce((total, score) => total + score, 0) / featuresScore.length;

console.log(averageScore);
/* 7.4

Mark Zuckerberg: “Apna website ka feature score bhi thik h bhaii🥰”

10. Aligning the features in a single line ~ join ~

Mark wanted to see all the features in a single line joining with (-) in a proper format, so he told Chris to use join function to align the features in a single line.

let features = ["post","like","comment","share","save"];
console.log(features.join('-'));
/*post-like-comment-share-save

Mark Zuckberg: “aab lag rha h thikk🤓”

So, this is how Mark was successful to create Facebook and operate. Thanks to JavaScript array methods which helped him to complete his task 😎
