JavaScript Development

JavaScript is a flexible and powerful programming language. HTML is responsible for structure and CSS is responsible for style, JavaScript provides interactivity to web pages in the browser. The importance of JavaScript as a web technology can be determined from the fact that it is currently used by 94.5% of all websites. So it will be wise not to bargain with the importance of JS.(😂) As a junior web developer you should know the following questions:

ES6 refers to version 6 of the ECMA Script programming language. It is a modern addition to JavaScript language, offers many more features that make large-scale software development easier. ECMAScript, or ES6 , was published in June 2015.Today I would like to share the key features that made ES6 much more effective.

1) Default Parameters in ES6 :

In ES6, we can put the default values right in the signature of the functions. That ‘s why you don’t need extra line to declare it.

var calculateTheArea = function(height = 10, width = 20) {
// write logic…

2) Variable Bindings :

When we introduce variable with var, let, and const , bindings are occurs and create scope there. To clear this let’s discuss the var keyword which is repeates everywhere in the script and its…

JavaScript, a high-level language known as interpreted, prototype-based & dynamic scripting language. Today I would like to share 10 basic concepts of JavaScript with you!

Firstly, Some Important JS Math method:

1) Math.abs( ): This Math. abs( ) function returns the absolute value of a number. The method returns a positive result to any negative or positive number.

//Firstly declare a function number that will give the absolute value.

function number(x, y) { return Math.abs(x ~y) };
console.log(number(1, 5));
// output: 4
console.log(number(5, 3));
// output: 2

2) Math.max( ): Math max( ) function is used to get the max number from a few numbers.

console.log(Math.max( 1, 5, 2, 9));
// output: 9
console.log(Math.max( 1, 55, 2, 88));
// output: 88
console.log(Math.max(-88, -10, -6, -2));
// output: -2

3) Math.min( ) : The Math min( ) function is used to get the min number from a few numbers.

console.log(Math.min(20, 30, 40, 50));
// output: 20
console.log(Math.min(-20, -30, -40, -50));
// output: -50

Now, let me introduce the Array methods of JavaScript. Array refers to a single variable that can contain different elements. It can contain different types of values.

4)Array.length: Array.length is used to find out the length of an array.
