Assignment Operator

Set the value for local and global variables.

Set or change the value of a variable

Use the assignment operator (:=) to set or change the value of a local variable or a global variable.

Declare a new local variable using the var statement and the assignment operator (:=). Like this:

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 for info on declaring a global variable.

After a global or local variable is defined, use the assignment operator (:=) to change the variable's value.

g = 42
num1 = 42

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.
