Now, Guys on the next episode I’m going to share a function to convert any string to capitalized in few seconds so you won’t need to do the manual process every time. Negative index counts back from the end of the array if fromIndex < 0, fromIndex + array.length is used. Thank you for watching/reading folks, if you found this informative and wanted to make me more content like this please support me on Patreon. Zero-based index at which to start searching, converted to an integer. Here one thing is notable is if we get a very first wrong match from that point further execution will be terminate and the result will be returned with a false value.

while in case of the second result it’ll compare every record with 0th index record (5) where it’s equal to all record so the output is given as true. Const result = allEqual() // output: trueĪs the first result shows, on 0th index record (3) won’t match to the first index record and it’ll return false from then only.
