Introduction: This article is for the beginners who want to have a brief look at the 10 key topics about react. First of all, React is a javascript library and it is created by facebook, we all have heard of it. Right? We can’t say react js to a complete framework because it is not a 100% solution for the web. To complete the tasks we need to include other libraries.

1.Let’s talk about Library VS Framework

To start with frameworks are beginner friendly as there are a lot of predefined solutions available, though for larger projects it can be…

In this article, I will try to give write down about three topics that are very interesting and I have also had so much fun while learning these topics.

const add=(num1,num2)=>{

return num1 +num2;

}

console.log(add);

const myName = “Habib”;

1.To find out the length of myName variable we simply can run,

console.log(myName.length); // output: 5

2.charAt(index) shows the character in the index, in our example, we can apply console.log(myName.charAt(2));//output: b.

3.We can also convert all the characters in a string into uppercase or lowercase.

console.log(myName.toUpperCase()); // HABIB

console.log(myName.toLowerCase()); // habib

4.Two array of strings or simply two string can be added together with ‘concat()’ mthod

const firstName = ‘Habibur’;

const lastName =…
