What keyword is used to define a variable as a constant in Avaloq Script?

In Avaloq Script, the keyword used to define a variable as a constant is "const." When a variable is declared with "const," it indicates that the variable's value cannot be changed after it has been set. This is particularly useful for creating values that should remain the same throughout the program execution, enhancing code readability and preventing accidental modifications.

Constants help maintain a systematic approach when dealing with fixed values, such as mathematical constants or configuration settings in the code. When using "const," the programmer can benefit from compile-time checks to ensure that the constant is not altered, which contributes to the stability and reliability of the script as a whole.

The other keywords mentioned—while related to variable management in different contexts—serve different purposes. "Final" typically denotes a variable that can be assigned only once but does not inherently convey that the value is immutable. "Static" refers to a variable with a lifespan tied to the class rather than an instance, and "immutable" is a concept that indicates that an object cannot be modified once created, but it is not a keyword used for declarations in Avaloq Script.
