+Jai strings are array views (slices) over `u8` and are not null-terminated. You can create string literals using double quotes:
+
+```jai
+message: string = "Hello, World!";
+length: int = message.count; // get string length
+
+// strings are just array views over u8
+data: *u8 = message.data; // get pointer to first byte
+
+// you can slice strings
+substring: string = message[0..5]; // "Hello"
+```
 
 Jai strings are are array views (slices) over `u8`, arrays are also not null terminated.
