As you can see in the last code snippet above, a variable declared inside a begin-end block is visible only in the specific block, and not after the block has terminated.
Scoping rules Variables declared by let have as their scope the block in which they are defined, as well as in any sub-blocks in which they aren't redefined.
The scope of a variable declared with var is its current execution context,which is either the enclosing function or, for variables declared outside any function, global.
If condition is adeclaration such as T t= x, the declared variable is only in scope in the body of the loop, and is destroyed and recreated on every iteration, in other words, such while loop is equivalent to.
また、ReDimステートメントは、Array型として宣言された変数上では使用できません。
Also, the ReDim Statement cannot operate on a variable declared as type Array.
This is an example of functional scoping: in JavaScript, the scope of a variable is defined by its location within the source code, and nested functions have access to variables declared in their outer scope.
Environment variablesdeclared inside a shell command run step, for example FOO=bar make install, will override environment variables declared with the environment and contexts keys.
