Introduction to Strings

Strings are a JavaScript type to store text values like "bob" or 'I like cheese'.

Strings can be created with single or double quotes.

"this is a string"
'this is a string, too'

When a number is surrounded by single or double quotes, it is actually a string!

'3'
"4.32"

Strings can be combined using the plus operator (+). This is called string concatenation.

console.log("bat" + "man"); // prints "batman" to the console

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

console.log("coolio".length); // prints 6 to the console

The "coolio" string has 6 letters so the length is 6.

console.log("sponge" + "bob");

"spongebob"

console.log("colombia".length);

8

console.log('i am'.length);
