Question 1 of 30

Can you describe how you would implement linear search in JavaScript?

"The easiest way to implement a linear search within JavaScript is to create an algorithm that examines each element in the list and determines whether it matches the value I have defined. Once I've created the algorithm, I can repurpose it by simply redefining the value and/or the list I am using."
