Conditional rendering is a term to describe the ability to render different user interface (UI) markup if a condition is true or false. Example :
{courseGoals.length > 0
&&
( <CourseGoalList items={courseGoals} />) }
if the first condition is true , the second element is rendered automatically , but if the 1st condition is false nothing is rendered , So (true && something) return " something " but ( false && something) return nothing .
