line 1: assign a number value to the variable x lines 3+6+9: The number in the brackets - the parameter - defines the number of decimal places to display the number value of x. The method converts the value of x to a string with fixed decimal places and stores it in a new variable y. NOTE: it is not necessary to store the value of toFixed() in a new variable. RECOMMENDATIONS: Use 0 as a parameter to round off numbers to a whole number. Use 2 when rounding off numbers for money.
