Hello, and welcome to today's JavaScript lesson! We are going to unravel a compelling challenge that will refine our skills in string manipulation. This lesson will place particular emphasis on nested loops
. Prepare yourself for an intriguing adventure as we explore how to extract odd-indexed characters from each word in a sentence, but only if the word has an even number of characters. Does that sound exciting? Let's dive in!
The task we'll be demonstrating is as follows: We will work with a string representing a sentence in which words are separated by spaces. Your challenge involves creating a JavaScript function that identifies the odd-indexed characters of words that have an even number of characters and then combines these characters into a single string, maintaining the order in which they appeared in the sentence.
Consider this example: "JavaScript programming language is versatile."
The word JavaScript
has 10 characters (an even number), and we'll select the odd-indexed characters from this word, specifically, a
, a
, c
, i
, t
. Similarly, we'll select a
, g
, , from , from , and , , , , from We'll skip the word because it has an odd length.
