toFixed()It rounds a number to a given number of digits and returns it in the form of a string.var x = 9.656;

x.toFixed(0); Output: 10

x.toFixed(2); Output: 9.66

valueOf()It returns the value of a variablevar x = 123;


Output: 123

Number()It converts variables into a number. It can also convert a date into a number.Number(new Date(“2019-05-01”));
