Variable Reassignment in Go

You can change the value stored in a variable with the assignment operator =.

myVar := 5
myVar = 10

fmt.Println(myVar) // Output: 10

The first line creates myVar. The second line reassigns it to a new value.

Assigning the value of one variable to another:

myVar := 5
myNum := 10

myVar = myNum

fmt.Println(myVar) // Output: 10

After the assignment, myVar has the same value as myNum.
