I know it will deal with return but putting it into code is what I am struggling with.

#SPLICE JS RETURN HOW TO#

The issue I am having now is that I do not know how to update the array to where it remembers that the previous selected number is not in roation anymore. This code so far shuffles a random song number and splices it out of an array. this outputs the randomlikedsong variable //helps me test the code } //i want to update the array that lists the new updated element list lets us use the index to splice out the element from the array the index in the array that equals the value of randomLikedSongĬonst index = listOfLikedSongs.indexOf(randomLikedSong) this choses a random element from the array

this makes an array from the length of likedSongs The next time I select a random number, there will be no possible way to get a repeat and this will continue till there are no more possible elements in the array left. The function returned is a curried function whose arity matches that of the highest-arity predicate. The slice method can return selected objects too, but it returns. For example, str.slice (1, 4) extracts the second character through the fourth character (characters indexed 1, 2, and 3 ). slice () extracts up to but not including inde圎nd. Changes to the text in one string do not affect the other string. This number will then be removed from the array of likedSongs, and then update the array to not include that number anymore. The second difference is that using Splice you can return an item to the original array. Description slice () extracts the text from one string and returns a new string. array.slice (from, until) From: Slice the array starting from an element index Until: Slice the array until another element index For example, I want to slice the first three elements from the array above.

I then want to randomly shuffle and get assigned a number. The slice ( ) method copies a given part of an array and returns that copied part as a new array. So in the most basic form, I have assigned a set value of likedSongs (10 songs) that will then be created into a list in an array (1-10). Just like how the music apps work, when you’re listening to music on shuffle, you will not get repeated songs. Hello all! I am working on a small ‘project’ that I thought of while driving and listening to music.
