  • JavaScript arrays allow you to group values and iterate over them.
  • You can add and remove array elements in different ways.

Removing an Element

Shift Method

To remove an element from the beginning of an array, we can use the shift method

	const days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'];

days.shift(); // returns the removed element, in this case "Monday"

console.log(days); // [ 'Tuesday', 'Wednesday', 'Thursday', 'Friday' ]

Slice Method

There is also a way to remove the first element from an array without changing the underlying array ,We can use the slice method.

	const days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'];

const newDays1 = days.slice(1);
const newDays2 = newDays1.slice(1);

console.log(newDays1); // [ 'Tuesday', 'Wednesday', 'Thursday', 'Friday' ]
console.log(newDays2); // [ 'Wednesday', 'Thursday', 'Friday' ]

As with other non-destructive methods, we need to assign the results to a new variable to save our changes
