For example, you might use the ternary operator to validate the inputs of a function or handle a flag.
Adam Spofford found this creative use of the ternary operator in a game he’s developing for:
this.worldUuid = builder.worldId == null ? null : builder.worldId; this.position = builder.position == null ? null : builder.position; this.rotation = builder.rotation == null ? null : builder.rotation; this.scale = builder.scale == null ? null : builder.scale; this.worldUuid = builder.worldId; this.position = builder.position; this.rotation = builder.rotation; this.scale = builder.scale;
Curious about how this specific block came to be, Adam poked through the Git history. For starters, the previous version of the code was the last four lines- the sane lines. According to
git blame, the project lead added the four ternary lines, with a git comment that simply read: “Constructing world details”. That explains everything.
