JavaScript provides a range of useful methods for working with numbers, facilitating various operations and conversions. The toFixed() method is employed to round a number to a specified decimal precision and return it as a string. Similarly, toPrecision() yields a string representation with a defined number of significant digits. The toString() method converts a number to a string, while parseInt() and parseFloat() parse strings into integers and floating-point numbers, respectively. The isNaN() function determines whether a value is Not a Number, and isFinite() checks if a number is finite. Additionally, the Number() function converts a value to a number, and various formatting methods like toFixed(), toPrecision(), and toString() aid in presenting numbers in desired formats. These methods collectively empower developers to manipulate and format numeric data efficiently in JavaScript.
