+
+### Touch Develop
+
+Use the assignment operator (:=) to set or change the value of a [local variable](/reference/variables/var) or a [global variable](/js/data).
+
+### Declare a variable
+
+Declare a new *local* variable using the [var](/reference/variables/var) statement and the assignment operator (`:=`). Like this:
+
+```blocks
+let num1 = 7
+let name = "Joe"
+```
+
+The variable's name is on the left of the assignment operator (`:=`) and the variable's value is on the right:
+
+*variable name* `:=` *value*
+
+See [global variable](/js/data) for info on declaring a global variable.
+
+### Change a variable
+
+After a global or local variable is defined, use the assignment operator (`:=`) to change the variable's value.
+
+```
+g = 42
+num1 = 42
+```
+
+### Notes
+
+* Don't confuse the assignment operator `:=` with the equality operator `=`, which is used to compare values.
+* You can use the assignment operator  `:=` with variables of each of the supported [types](/js/types).
