"<code>function functionName(a, b) {</code>",

"We can \"call\" our function like this: <code>functionName();</code>, and it will run and return its <code>return</code> value to us.",
"Create and call a function called <code>myFunction</code> that returns the sum of a and b."
"After writing the above lines in our code, we can then pass values to our function and the result following the <code>return</code> statement will be returned.",
"For example, we can pass numbers <code>4</code> and <code>2</code> by “calling” the function later in our code like this: <code>functionName(4, 2)</code>.",
"In this example, the function will return the number <code>6</code> as this is the result of <code>4 + 2</code>.",
