// Using the spread operator and slice() method:

const array = [1, 2, 3, 4, 5];
const indexRemove = 2;   // Remove the element at index 2 (3)

const newArray = [...array.slice(0, indexRemove), ...array.slice(indexRemove + 1)];
console.log(newArray);   // Output: [1, 2, 4, 5]

const array = [1, 2, 3, 4, 5];
const indexRemove = 2;	// Remove the element at index 2 (3)

const newArray = array.filter((element, index) => index !== indexRemove);
console.log(newArray);  // Output: [1, 2, 4, 5]

/*
 	The filter() method creates a new array by iterating over 
    the original array and keeping only the elements 
    that pass a specified test function.
