    Apart from subject knowledge and skills , the modulation of voice is very important for a teacher. Some teachers despite having crystal clear concepts , irritates when speak.
    Your voice is crisp and delivery is smooth. Hats off to you.

    I wonder who are the 272 people disliking this; it was very clear; only thing I would say is to mention the termination condition more explicitly; when low = high which is checked by the if happens when we get to the leaf node. Might not be immediately clear the importance of the initial if statement to new student. Some might write while(low !== high) or if(low !== high). Beautifully taught.
