JavaScript Array Methods are incredibly powerful, but learning them can sometimes be boring. ๐คฏ What if we relate them to Indian politics? It will not only make learning easier but also more fun! ๐
Today, weโll understand 10 JavaScript Array Methods with examples from Indian politics. Letโs begin this exciting journey! ๐
1. push() โ Adding a New Party or Leader
Function: push()
adds a new item at the end of an array.
Political Example: When a new leader joins a political party.
let politicalParties = ["BJP", "Congress", "AAP"];
politicalParties.push("TMC");
console.log(politicalParties);
// ["BJP", "Congress", "AAP", "TMC"]
๐ TMC (Trinamool Congress) has now joined the list of political parties!
2. pop() โ Removing a Leader or Party
Function: pop()
removes the last item from an array.
Political Example: When a leader leaves a party.
let politicalParties = ["BJP", "Congress", "AAP", "TMC"];
politicalParties.pop();
console.log(politicalParties);
// ["BJP", "Congress", "AAP"]
๐ TMC has now been removed from this list!
3. shift() โ Removing the Oldest Party or Leader
Function: shift()
removes the first item from an array.
Political Example: When an old party dissolves or a veteran leader retires.
let politicalParties = ["Janata Dal", "BJP", "Congress", "AAP"];
politicalParties.shift();
console.log(politicalParties);
// ["BJP", "Congress", "AAP"]
๐ Janata Dal is no longer part of Indian politics!
4. unshift() โ Revival of an Old Alliance
Function: unshift()
adds a new item at the beginning of an array.
Political Example: When an old party revives and comes back into the limelight.
let politicalParties = ["BJP", "Congress", "AAP"];
politicalParties.unshift("Shiv Sena");
console.log(politicalParties);
// ["Shiv Sena", "BJP", "Congress", "AAP"]
๐ Shiv Sena is back in the spotlight!
5. splice() โ Replacing or Removing a Leader
Function: splice()
adds, removes, or replaces elements in an array.
Political Example: When a leader is removed from a party or replaced by another.
let leaders = ["Narendra Modi", "Rahul Gandhi", "Arvind Kejriwal"];
leaders.splice(1, 1, "Amit Shah");
console.log(leaders);
// ["Narendra Modi", "Amit Shah", "Arvind Kejriwal"]
๐ Rahul Gandhi is replaced by Amit Shah!
6. slice() โ Forming a New Political Group
Function: slice()
extracts a portion of an array and creates a new array.
Political Example: When a faction of a party breaks away and forms a new alliance.
let parties = ["BJP", "Congress", "AAP", "TMC"];
let newAlliance = parties.slice(1, 3);
console.log(newAlliance);
// ["Congress", "AAP"]
๐ Congress and AAP have formed a new coalition!
7. filter() โ Selecting Honest Leaders
Function: filter()
selects items from an array based on a condition.
Political Example: Filtering out only non-corrupt leaders.
let leaders = [
{ name: "Narendra Modi", honest: true },
{ name: "Rahul Gandhi", honest: false },
{ name: "Arvind Kejriwal", honest: true }
];
let honestLeaders = leaders.filter(leader => leader.honest);
console.log(honestLeaders);
// [{ name: "Narendra Modi", honest: true }, { name: "Arvind Kejriwal", honest: true }]
๐ Only the honest leaders remain in the list!
8. map() โ Changing the Ideology of All Parties
Function: map()
applies a transformation to each element in an array.
Political Example: Making every party work for "national interest."
let parties = ["BJP", "Congress", "AAP"];
let transformedParties = parties.map(party => party + " (National Interest)");
console.log(transformedParties);
// ["BJP (National Interest)", "Congress (National Interest)", "AAP (National Interest)"]
๐ Now, all parties claim to work for the national interest!
9. reduce() โ Counting Total Seats in an Election
Function: reduce()
combines all elements in an array into a single value.
Political Example: Counting the total seats won by all parties in an election.
let seats = [303, 52, 62, 22];
let totalSeats = seats.reduce((total, num) => total + num, 0);
console.log(totalSeats);
// 439
๐ The total number of seats won by all parties is 439!
10. find() โ Finding the Most Popular Leader
Function: find()
returns the first element that meets a condition.
Political Example: Finding the leader with more than 100 million followers.
let leaders = [
{ name: "Narendra Modi", followers: 150 },
{ name: "Rahul Gandhi", followers: 30 },
{ name: "Arvind Kejriwal", followers: 20 }
];
let popularLeader = leaders.find(leader => leader.followers > 100);
console.log(popularLeader);
// { name: "Narendra Modi", followers: 150 }
๐ Narendra Modi is the most followed leader!
