By the word Array methods, I mean the inbuilt array functions, which might be helpful for us in so many ways. So why not just explore and make use of them, to boost our productivity.
Let’s see them together one by one with some amazing examples.
_fill()_method changes all elements in an array to a static value, from a start index (default
_0_) to an end index (default
_array.length_). It returns the modified array.
In simple words, it’s gonna fill the elements of the array with whatever sets of params, you pass in it. Mostly we pass three params, each param stands with some meaning. The first param value: what value you want to fill, second value: start range of index(inclusive), and third value: end range of index(exclusive). Imagine you are going to apply this method on some date, so that how its gonna look like eg: array.fill(‘Some date’, start date, end date).
NOTE: Start range is inclusive and end range is exclusive.
Let’s understand this in the below example-
//declare array var testArray = [2,4,6,8,10,12,14]; console.log(testArray.fill("A"));
When you run this code, you gonna see all the elements of
testArray will be replaced by
array.splice(startIndex, deleteCount[, item1, item2, …])
