Click to see additional instructions Read the W3 documentation on the String object substring() method (recall a method is when a property of an object is a function). Fill in the values for the two function arguments below to make the statement output what is described: var alphabet = 'abcdefghijklmnopqrstuvwxyz'; console.log('letters f through p in the alphabet are + alphabet.substring( ); Click to see additional instructions Read the argument Accepted characters: numbers, decimal point markers, sign indicators (-), spaces (e.g., as thousands separator, 5 000), p). Fill in the values for the two function "E" or "e" (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker. var alpha Complex numbers should be in the form {a + bi} where "a" and "b" need to have explicitly stated values. For example: {1+11} is valid whereas {1+1} is not. {0+9i} is valid whereas {9i} is not. console ); To define a code block as a function called addEmUp() with parameters x and y you must start it with the function keyword and give the parameters desired within ()'s. This declares and initializes a function data type which can then be assigned to a variable as follows (fill in the blanks to make a correct and complete function definition): var addEmUp = return x + y; } For readability and convenience, this can also be done as follows: addEmUp ( return x + y; }
