// Write a JavaScript program that creates a class called Bank with properties for bank names and branches. Include methods to add a branch, remove a branch, and display all branches. Create an instance of the Bank class and perform operations to add and remove branches.

    if (index !== -1) {
      this.branches.splice(index, 1);
    }

    console.log(`Branches of ${this.bankName}:`);
    for (const branch of this.branches) {
      console.log(branch);

// Create an instance of the Bank class
