Learn Array Methods Easily with Barcelona's Approach
Welcome to the Blog, it’s a fun and hands-on way to learn Array methods in JavaScript.
So SIT BACK, RELAX, and enjoy the show
AND TO MAKE IT EVEN MORE WE HAVE …DRUMROLLLSSS….
BARCELONA🎉🎉🎉
So here’s the squad of Barcelona 2025-26 Season
let team = new Array("Joan Garcia","Jules Koundé","Pau Cubarsí","Gerard Martín","Alejandro Balde"," Frenkie de Jong","Pedri","Fermín López","Lamine Yamal","Raphinha","Lewandowski",);
// The above code represent the array of Barca 11 , 2025-26 season
YOU ARE APPOINTED AS THE NEW MANAGER OF BARCELONA, AND YOU HAVE TO ACHIEVE 10 OBJECTIVES TO MAKE THE CLUB BETTER
OBJECTIVE #1 - TALK WITH Robert Lewandowski.
let team = new Array("Joan Garcia","Jules Koundé","Pau Cubarsí","Gerard Martín","Alejandro Balde"," Frenkie de Jong","Pedri","Fermín López","Lamine Yamal","Raphinha","Lewandowski",);
// The above code represent the array of Barca 11 , 2025-26 season
console.log(team.include("Lewandowski");
The include() method is used to find whether the array includes a certain value and return a Boolean value
OBJECTIVE #2 - DUE TO Robert Lewandowski's Age, YOU HAVE TO REMOVE HIM FROM THE Squad
let team = new Array("Joan Garcia","Jules Koundé","Pau Cubarsí","Gerard Martín","Alejandro Balde"," Frenkie de Jong","Pedri","Fermín López","Lamine Yamal","Raphinha","Lewandowski",);
// The above code represent the array of Barca 11 , 2025-26 season
console.log(team.pop())
//removing and returning last element(player)
console.log(team)
// the squad after removing Lewandowski
OBJECTIVE #3 - PROMOTE 2 LA MASIA GRADUATES INTO THE FIRST TEAM
let team = new Array("Joan Garcia","Jules Koundé","Pau Cubarsí","Gerard Martín","Alejandro Balde"," Frenkie de Jong","Pedri","Fermín López","Lamine Yamal","Raphinha","Lewandowski",);
// The above code represent the array of Barca 11 , 2025-26 season
let UpdatedSquad = team.push("Dro","Toni");
//2 LA MASIA GRADUATES(NEW VALUES TO ADD IN ARRAY)
console.log(team);
So the Push method is like Repairo(Harry Potter reference), it will fix all your problems related to the squad as the Manager, as you can add any value/Variable(Player) in the array(squad)
OBJECTIVE #4 - TALK WITH Gerard Martín and Alejandro Balde about the team's defensive action, but don’t inform other players
let team = new Array("Joan Garcia","Jules Koundé","Pau Cubarsí","Gerard Martín","Alejandro Balde","Frenkie de Jong","Pedri","Fermín López","Lamine Yamal","Raphinha","Lewandowski",);
// The above code represent the array of Barca 11 , 2025-26 season
console.log(team.slice(3,5))
The slice Method in JavaScript takes 2 parameters (Start, End) and returns the values that are between the given parameters
In this case, Gerard Martín and Alejandro Balde are in 4th and 5th place, respectively, so we took ( 3,5) as (Start, End) Parameters
OBJECTIVE #5 - SIGN RASHFORD FROM MAN UTD ON A LOAN DEAL TO MAKE THE SQUAD STRONGER
let team = new Array("Joan Garcia","Jules Koundé","Pau Cubarsí","Gerard Martín","Alejandro Balde","Frenkie de Jong","Pedri","Fermín López","Lamine Yamal","Raphinha","Lewandowski",);
// The above code represent the array of Barca 11 , 2025-26 season
let ManUtd = new Array("rashford", "garnacho", "bruno fernandez", "sesko");
//Taking rashford on Loan from Man UTD
team.unshift(ManUtd[0]);
console.log(team);
The unshift() method of Array instances adds the specified elements to the beginning of an array and returns the new length of the array.
I will add More Objectives in the near future so you can refer to the MDN documentation
till then PEACE 🕊️✌️
