In most standards, parameters (or formal parameters) are what’s given in the function declaration, and arguments (or actual parameters) are what’s passed to the function. In simple words, the operator is a character that defines an action or process. It takes more than one or one argument and generates a new value.

Nevertheless, for the purpose of this tutorial, we will make a distinction. Today, ECMAScript 6 is in the process of being finalized. Operators In a programming language, the Operators are some special functions used to perform some operation on the variables. Arguments Versus ParametersĪrguments and parameters are often referred to interchangeably.

In this tutorial, we will explore arguments and parameters in detail and see how ECMAScript 6 has upgraded them.

We can now use rest parameters, default values and destructuring, among other new features. In this tutorial, you’ll learn how ECMAScript 6 has upgraded parameter handling in JavaScript, and more.ĮCMAScript 6 (or ECMAScript 2015) is the newest version of the ECMAScript standard and has remarkably improved parameter handling in JavaScript. 5.2.6 Value Notation 6 ECMAScript Data Types and Values 6.1 ECMAScript Language Types 6.1.1 The Undened Type 6.1.2 The Null Type 6.1.3 The Boolean Type 6.1.4 The String Type 6.1.4.1 StringIndexOf ( string, searchValue, fromIndex) 6.1.5 The Symbol Type 6.1.5.1 Well-Known Symbols 6.1.6 Numeric Types 6.1.6.1 The Number Type 6.1.6.1. Developers are using ECMAScript 6 features more and more, and soon these features will be unavoidable.
