However, you can declare the variables anywhere in JavaScript. But, the location of the declaration determines the extent of a variable's availability within the JavaScript program i.e. where the variable can be
Function declarations are probably the most familiar and oldest way of doing things in JavaScript land. This creates a variable A which is accessible in the current scope. Scope is a separate topic, so well do everything in the global scope for all these examples (something you want to avoid...
Enums in TypeScript can be verbose, so sometimes it is desirable to compile a dropdown to a constant variable rather than an enum member (for example,Item.Shovelcould instead beSHOVEL). To achieve this behavior, setemitAsConstantto true on an enum //% emitAsConstant enum Item { //% bl...
By implementing an application feature lifecycle listener class, you enable an application feature to automatically obtain any data changes to the applicationScope variable or to application feature-specific variables that changed when the application feature was deactivated. Table 5-4 describes when the ...
In Schedule.jsx: A new state variable (openedDays) is used to record each day (using its midnight timestamp) that has been opened. The handleOpenDate function now checks if a day has already been opened before adding shifts. When generating the "Open Shift" events (all-day events) for ...

We will also need to pass in two uniform variables. The u_translate variable will be used by the vertex shader to translate the position of the sprite, and u_texture is a texture buffer that will be used by the fragment shader. These shaders are almost as simple as they get. Many ...
There is no node in the browser, so it makes no sense. Here is my rule of thumb. First of all keep your code similar as possible through all the environments and keep NODE_ENV always on ‘production’. Second, if you have to use differentiation, make a new variable for your environmen...
toggle word wrap toggle overflow from("spark-rest:get:/say/hello/:name").transform().simple("hello ${header.name}"); from("spark-rest:get:/say/hello/:name").transform().simple("hello ${header.name}"); notice that, in contrast to the rest component, the syntax for a variable in ...
Most webapplications today rely on included libraries, frameworks, and APIs. In many cases, the include statement contains a relative path or uses a variable containing a hardcoded path to make it easier to change the location of the remote code later. When a hacker is able to gain access ...
