Reversing a string appears to be a straightforward task, right? Simply re-arrange the letters in the opposite order.
However, when thinking algorithmically, we must be precise. We must dissect each step of the reversal and consider potential flaws in the process.
split() returns the new array after splitting a text into an array of substrings with a separator.
reverse() - This method reverses the order of an array's elements. The first element transforms into the last, and the element transforms into the first.
join() combines all members of an array into a single string and returns it.
- To begin, type <! DOCTYPE html> into your browser's address bar to inform it that the file is in HTML format.
- The <html> element, on the other hand, is used to signal the start of HTML content.
- The <head> tag now contains the information about web pages. The < title> element is used in this tag to provide a web page title. For example, the <head> and < title> tags are paired tags. As a result, both have the </head> and </title> closing tags.
- Using split, we have divided the input string into an array of its letters (). Make careful to use the split method with an empty string, such as split("). This guarantees that the split method breaks the string into its constituent characters.
- By using reverse, we have reversed the array of letters ().
- We have used join to unite the array of reversed letters into a string (). Make that the join method includes an empty string, such as join("). This guarantees that the connect method puts the letters together without any gaps.
- The < /body> and </html> tags are used to close the body and html tags, respectively.
