"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."

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.
