used for holding text
3 ways to create strings:
1. using single quotes:
  
  const first = 'Soumya';
2. using double quotes:
  
  const middle = "Ranjan";
3. using backticks:
```
 	const last = `Mohanty`;
```
single quotes and double quotes are the same thing.

used for: "she's cool"

or escaping: 'she\\'s cool'

backticks:

  const sentence = `she's so "cool"`;
  console.log(sentence); // she's so "cool"

Multi-line string:

  const song = 'Oh \\
  I like \\
  pizza';
  
  console.log(song); // Oh I like pizza

  const song = `Oh
  I like
  pizza`;
  
  console.log(song); 
  /*
  Oh
  I like
  pizza
  */

2nd one using backticks is mostly used.

String concatenation and interpolation
- '+' is used for concatenation. It is also used for adding 2 nos.
- Concatenation: when 2 or more strings combined to one
- Interpolation: when you put a variable inside a string
- Example 1:
const name = 'Soumya';

const hello = 'Hello my name is ' + name + '. Nice to meet you.'

(can use double or single quotes)
- Example 2:
1+1 // 2

'1'+'1' // 11

1 + '1' // 11
- Example 3:
  
  const name = 'Soumya'; const hello = Hello my name is ${name}. Nice to meet you. I am ${100+1} years old.; console.log(hello); // Hello my name is Soumya. Nice to meet you. I am 101 years old.
- Backticks also used for tagged template literals.
- Backticks are helpful for creating HTML:
```
  const html = `
  	<div>
  		<h2>Hey everyone! I am ${name}.</h2>
  	</div>
  `;
```
