### Declare a variable
2016-04-13 17:27:45 +02:00
Declare a new *local* variable using the [variable](/reference/variables/var) statement and the assignment operator. Like this:
2016-03-26 00:47:20 +01:00
````blocks
let num1 = 42;
let name = "Joe";
````
The variable's name is on the left of the assignment operator and the variable's value is on the right:
````blocks
let num1 = 42
````
### Notes
2016-04-13 17:27:45 +02:00
* You can use the assignment operator with variables of each of the supported [types](/blocks/types).
