Measuring the size of each item within a given array

Question

Measuring the size of each item within a given array

In my quest to determine the length of each word in a lengthy text, I am seeking assistance. I aim to return an array containing the length of every word at the conclusion of this function.

My current approach involves utilizing two loops - one to separate the text into individual words, and another to calculate the length of each word. However, I have been unable to make this strategy work effectively.

If you possess any innovative solutions to offer, I would greatly appreciate your help with resolving these challenges! Also, it is worth noting that I am relatively new to JavaScript, so I kindly ask for your patience as I navigate through this learning process.

Answer 1

Answer №1

Here is a snippet that creates an array of objects with words and their lengths:

let sentence = 'Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua';
let wordArray = sentence.split(' ').map((word) => {
    return {
        word: word,
        length: word.length
    }
});

I trust this will be beneficial to you!

To break down a sentence into individual words, you can utilize the String.prototype.split() method and specify a space ' ' as the separator. To iterate through this array and create a new array based on certain criteria, you can use Array.prototype.map(). Your function could look something like this:

'Hi there!'.split(' ').map((word) => (word.length));

However, why does it return `[1, 6]`? The reason is that your function doesn't account for characters like "!" in the word count.

There are different approaches to handling this. You could consider returning [1, 5], [1, 5, 1], or sticking with [1, 6].

If you prefer the first option, you might use a regular expression like this:

'Hi there!'.split(/\b\W*/).filter(Boolean).map((word) => (word.length));
// 'filter(Boolean)' removes empty strings added by split()

This approach will treat the word "time-out" as [4, 3]

Alternatively, for the second option, you can try:

'Hi there!'.split(/\b\s*/).map((word) => (word.length));

Using this will give you "I'm" as [1, 1, 1]. Ultimately, finding the most suitable regex pattern depends on defining where a word begins and ends, which can be subjective.
