Reorganizing an array while initializing it in Javascript

Upon further review of responses, I have decided to exclude single characters, code, and special characters from the initial creation of the words array.

Utilizing the script found at THIS PAGE and executing it in the console on any website, we obtain an array of thousands of words that has already been sorted as "words".

To extract the top 25 words, you can use the following code snippet:

cleanArray = words.slice(0, 25);
console.log(cleanArray);

The goal is to cycle through the words array and eliminate any element that consists of only one character or contains special characters/code tags.

I am contemplating whether it's more efficient to perform this action after the words array is constructed or during its construction process.

Answer №1

In some cases, it may be more efficient to avoid adding elements to an array initially because removing them later would require extra steps, resulting in wasted actions.
However, there are scenarios where skipping entries during the creation process is not feasible, such as when using string split.

It's always a good practice to minimize unnecessary work and if unsure, consider benchmarking.
