Objects are collections of key-value pairs, while arrays are ordered collections of values.

Objects and arrays both store data in key-value pairs.

Objects are ordered collections of values, while arrays are collections of key-value pairs.

Arrays are unordered collections of values, while objects are ordered collections.

Arrow functions are only used for mathematical calculations, traditional functions are used for all other purposes

Traditional functions require explicit return statements, while arrow functions automatically return the result of the expression.

Arrow functions do not have their own 'this' keyword and cannot be used as constructor functions with 'new', whereas traditional functions have their own 'this' context and can be used with 'new'.

Arrow functions cannot accept arguments, traditional functions can accept multiple arguments

Math.subtract() for subtraction operations, Math.infinity for representing positive infinity, Math.multiply() for multiplication operations

Some common math functions and constants in JavaScript include Math.sqrt() for square root, Math.PI for the value of pi, and Math.round() for rounding a number to the nearest integer.

Math.factorial() for calculating factorial, Math.e for the base of the natural logarithm, Math.floor() for rounding down to the nearest integer

Math.log() for logarithmic functions, Math.random() for generating random numbers, Math.abs() for absolute value

Arrays of objects require a special constructor function in JavaScript

You can create an array of objects by defining an array and assigning objects to its elements using object literal notation.

You can only create arrays of primitive values in JavaScript

Objects cannot be stored in arrays in JavaScript
