Join me as I walk through the problem statement: given a list of strings and a list of queries, our goal is to return an array that counts the occurrences of each query in the input strings. I'll demonstrate my approach using JavaScript, showcasing efficient techniques to solve this challenge with ease.
Watch as I break down the solution step-by-step, from understanding the input format to implementing a concise function that leverages list comprehension for optimal performance. Whether you're a beginner or looking to refine your skills, this video will provide valuable insights into handling string manipulations and counting occurrences effectively.
