Describe to me how you would implement a linear search in JavaScript.
The interviewer will ask you this question to better understand how you use algorithms and data structures when programming. It also provides them insight into your knowledge of JavaScript. They are interested in your skills in this and other areas related to this job. These types of questions are used to screen candidates and will usually be asked in the middle or heart of the interview, after the general questions, and before they ask you if you have any questions for them.
"The most common use of a linear search is to locate a specific target value within a data list. The algorithm is written in such a way that it examines each element of the list to see if it matches the values defined within the query."
When preparing for an interview for a senior software engineer's role in which you will be doing front-end or full-stack web development, you will want to refresh yourself on JavaScript, the commands it uses, and its programming structure. You are sure to be asked about each of these topics throughout the interview. One of the key skills the interviewer will be looking for is your ability to create algorithms within JavaScript to accomplish specific tasks.
Community answers are written by other candidates practicing this set. Reading how others frame the same question is one of the fastest ways to sharpen your own.

If I needed to find a value in an array, for example, I could use a loop such as a for loop or a forEach call to iterate over the array and compare each element to the desired value.

Good job. Using a for loop is a great way to implement a linear search in JavaScript.
