In this short tutorial, we learn about the JavaScript string length property.

The JavaScript String length property returns the number of characters in a string.

Syntax

The syntax to use the length property is as follows

			
					str.length

			
	

			
	
			

		
	

• Here, str is a string.

Returns

• The length property returns an integer value that represents the number of characters in the string.
• If the string is an empty string, the length property will return 0.

Examples

			
					const helloWorld = "Hello World";

console.log(helloWorld.length)

			
	

			
	
			

		
	

OutPut

			
					11

			
	

			
	
			

		
	

			
					const emoji = '😇';

console.log(emoji.length);

			
	

			
	
			

		
	

OutPut

			
					2

			
	

			
	
			

		
	

The .length property will return 0 for empty strings

			
					console.log("".length);

			
	

			
	
			

		
	

OutPut

			
					// 0

			
	

			
	
			

		
	

• You can even use it directly to any string you encounter

			
					console.log("My Name is Adam".length)

			
	

			
	
			

		
	

OutPut

			
					15

			
	

			
	
			

		
	

Notes:

• The String.length property is a read-only property. Means if we try to change it manually there will be no effect.
• The String.length property actually returns the code units in the UTF-16 string format.You Can use this link to read more about UTF-16
