Shivam Payasi · Answer

In JavaScript, helper methods are functions that are created to assist or simplify common tasks. Here are some commonly used helper methods in JavaScript: 1. `parseInt()` - Converts a string into an integer. 2. `parseFloat()` - Converts a string into a floating-point number. 3. `toFixed()` - Formats a number to a specified number of decimal places. 4. `toString()` - Converts a value to a string. 5. `toLowerCase()` - Converts a string to lowercase. 6. `toUpperCase()` - Converts a string to uppercase. 7. `length` - Returns the length of a string or array. 8. `split()` - Splits a string into an array of substrings based on a specified separator. 9. `join()` - Joins all elements of an array into a string. 10. `push()` - Adds one or more elements to the end of an array and returns the new length. 11. `pop()` - Removes the last element from an array and returns that element. 12. `indexOf()` - Returns the first index at which a given element can be found in an array, or -1 if it is not present. 13. `includes()` - Determines whether an array contains a certain element, returning true or false as appropriate. 14. `slice()` - Extracts a section of an array and returns a new array. 15. `concat()` - Combines two or more arrays and returns a new array. 16. `Math.random()` - Generates a random number between 0 and 1. 17. `Math.floor()` - Rounds a number down to the nearest integer. 18. `Math.ceil()` - Rounds a number up to the nearest integer. 19. `Math.max()` - Returns the largest of zero or more numbers. 20. `Math.min()` - Returns the smallest of zero or more numbers. These are just a few examples of helper methods in JavaScript. There are many more built-in helper methods available in JavaScript, and developers can also create their own custom helper methods to simplify their code.
