How do I manipulate arrays in JavaScript?
You can manipulate arrays in JavaScript using methods like push, pop, shift, unshift, splice, and slice.
Can you explain the difference between splice and slice?
Sure! splice
changes the contents of an array by removing or replacing existing elements and/or adding new elements. slice
, on the other hand, returns a shallow copy of a portion of an array without modifying the original array.
How do I remove duplicates from an array?
You can remove duplicates using the Set
object or by filtering the array. For example: const uniqueArray = [...new Set(array)];
.
What about sorting an array?
You can sort an array using the sort()
method. For example: array.sort((a, b) => a - b);
for numerical sorting.
