Use concatenation to join two strings together.
Use interpolation to embed JavaScript expressions inside a string (ES6).
HINT: Create a variable and store a string value inside it. Then embed this variable inside a string using interpolation (template literals syntax).

Define an Array of names (strings) and store it in a variable.
Use one of the discussed loop techniques to iterate over the Array and select names which starts with B.
Inside the loop, use an if condition and compare the first character of each name with the letter B.
HINT: You may need to define second array to store the matching results. You can use console.log() to see the what is stored inside your variables.

Let's refactor the previous exercise and use a function (use any type of function you'd like).
The function takes two parameters: one represents a list of names and the other represents the first letter to filter with.
Once you've created the function, call it with two arguments: a list of names (Array) and a letter (String).
HINT: Inside your function, don't forget to return the result.
