In Ruby, the keywords this and that are not used to refer to specific objects or variables. However, you can assign values to variables using the assignment operator =.
For example, if you want to assign the value 5 to a variable named num, you can write:
num = 5
If you want to assign a string value to a variable named name, you can write:
name = "John Doe"
You can also assign the value of one variable to another variable using the assignment operator:
x = 10
y = x
In this case, the value of the variable x (which is 10) is assigned to the variable y.
You can also assign the result of an expression or method to a variable. For example, if you want to assign the result of adding two numbers x and y to a variable called sum, you can write:
x = 15
y = 20
sum = x + y
In this case, the sum variable will be assigned the value of 35.
