👉 In programming, "~" in a variable denotes that the value of that variable will be modified when you assign it to another variable or use it for further processing. The "~" character represents an assignment operator in many languages. It signals that the value stored at this location in memory has changed and needs updating or is being reassigned. This operator can be used with other variables, functions, or expressions. For example: ``` let x = 10; let y = ~x; // assigns a new value to y ``` The "~" operator also allows you to specify an initial value for the variable when it is first assigned. In this way, "~$variable" can be used instead of "$variable".
