| 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 variable | var x = 123; x.valueOf(); Output: 123 |
| Number() | It converts variables into a number. It can also convert a date into a number. | Number(new Date(“2019-05-01”)); Output: 1556668800000 |
