# Assignment Operator
Set the value for local and global variables #docs #assignment #language #var #data
### @parent blocks/operators
Set or change the value of a variable
````blocks
let item = 0
````
Use the assignment operator to set or change the value of a [variable](/microbit/reference/variables/var).
### Declare a variable
Declare a new *local* variable using the [variable](/microbit/reference/variables/var) statement and the assignment operator. Like this:
````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
* You can use the assignment operator with variables of each of the supported [types](/microbit/blocks/types).
