Javascript Math sinh() Function Example

If you want to find the hyperbolic sine value of a given argument in JavaScript, then use the Math.sinh() method is used. The Math.sinh() method comes handy in programming contexts dealing with any trigonometric expressions. The sinh() is a static method of Math, and it can be used without creating an object.

Javascript Math.sinh() function returns the hyperbolic sine of a number that can be expressed using the constant e.

The Difference Between Regular Functions and Arrow Functions in JavaScript

Other then the syntactical differences. The main difference is the way the this keyword behaves? In an arrow function, the this keyword remains the same throughout the life-cycle of the function and is always bound to the value of this in the closest non-arrow parent function. Arrow functions can never be constructor functions so they can never be invoked with the new keyword. And they can never have duplicate named parameters like a regular function not using strict mode.

Here are a few code examples to show you some of the differences

this.name = "Bob";
const person = {

name: “Jon”,
<span style="color: #008000">// Regular function</span>
func1: <span style="color: #0000ff">function</span> () {
    console.log(<span style="color: #0000ff">this</span>);
},

<span style="color: #008000">// Arrow function</span>
func2: () =&gt; {
    console.log(<span style="color: #0000ff">this</span>);
}

}
person.func1(); // Call the Regular function

// Output: {name:“Jon”, func1:[Function: func1], func2:[Function: func2]}
person.func2(); // Call the Arrow function

// Output: {name:“Bob”}

The new keyword with an arrow function

const person = (name) => console.log("Your name is " + name);
const bob = new person("Bob");
// Uncaught TypeError: person is not a constructor

Function Expression vs Function Declaration in JavaScript

Function Expression vs Function Declaration in JavaScript.

It was until during one of the JavaScript mock interviews did I came across the term function expression.

The question was: What is the difference between these two syntax?

function x(){

}

let x = function(){

}

I was clueless for a moment. After thinking a little, I could only come up with: the second syntax invokes an _anonymous _function and is assigned to a variable.

I was alien to the term hoisting.

In this article, we will acquaint ourselves with three simple terms: function declaration,_ function expression, _and hoisting.

What is function declaration?

Function declaration is also known as _function statement. _It contains the name of the function, parameters, and a return statement. **Naming the function **is what sets function declaration apart. Parameters and return statement is optional.

Function Declaration

What is function expression?

Function expression also has a name, parameters, and return statement. All of which are optional. The important thing to bear in mind is: the function here is _assigned _to a JavaScript variable.

The real reason why JavaScript has arrow functions

Nowadays, all my code is based on the use of arrow functions. If you are still not using them yourself, then don’t be ashamed of who you are. That’s your parent’s job. Instead, find about all the benefits that you can get by using arrow functions like the cool kids.

This is an example of arrow function and the same code written traditionally:

const arrowFunction = (arg1, arg2) => arg1 + arg 2;

const traditionalFunction = function(arg1, arg2) {
  return arg1 + arg2;
};

You may notice that the code is shorter and that there is an arrow. Everything before the arrow is arguments of the function and everything after the arrow is always returned as the result of the function.

If you need a function that contains multiple statements you can still do this:

const arrowFunction = (arg1, arg2) => {
  const result = arg1 + arg2;
  return result;
};
