Day 2: Conditional Statements: If-Else (10 Days of Javascript)

Task:

Complete the getGrade(score) function in the editor. It has one parameter: an integer,score, denoting the number of points Julia earned on an exam. It must return the letter corresponding to her grade according to the following rules:

• If 25<score<=30, then grade=’A’.
• If 20<score<=25, then  grade=’B’.
• If 15<score<=20, then  grade=’C’.
• If 10<score<=15, then  grade=’D’.
• If 5<score<=10, then  grade=’E’.
• If 0<=score<=5, then  grade=’F’.
