In this exercise we are going to practice validating a password to confirm it contains letters and numbers using simple regular expressins. This exercise uses if statements to find a valid password instead of finding an invalid one. Inside the if statement that is already in the checkPassword(e) function: Create 2 variables, reA and reB. Assign one of the variables the regular expression for a number, assign the other the regular expression that will match any uppercase or lowercase letter. Place your regular expressions between //. Unlike the examples in lecture, you do not want to use ^ at the start of your regular expression or the $ at the end because that requires that you match ALL characters in the string instead of just looking for one. Create a second if statement (nested inside the first if statement) that checks if the password matches both regular expression variables: Call the test method on reA and pass it the value of the password entered in the pwd input. Call the test method on reB and pass it the value of the password entered in the pwd input. Note: Use a single if statement that checks that both of these validation conditions are true. Inside the body of the nested (inner) if statement: Set the disabled property of the submit variable to true (because the element passed validation). return true

Assume that minutes is an int variable whose value is 0 or positive. write an expression whose value is "undercooked" or "soft-boiled" or "medium-boiled" or "hard-boiled" or "overcooked" based on the value of minutes. in particular: if the value of minutes is less than 2 the expression's value is "undercooked"; 2-4 would be a "soft-boiled", 5-7 would be "medium-boiled", 8-11 would be "hard-boiled" and 12 or more would be a "overcooked".
