Just like how preorder traversal is used to generate a prefix expression from a tree, we use postOrder traversal to generate a postfix expressionReverse Polish Notation. For example, this infix expressionA - (B + C) + (D + E)can be converted to a postfix expression"A B C - * D E ...
To be specific: Regardless of whether top-levelawaitis used, modules always initially start running in the same post-order traversal established in ES2015: execution of module bodies starts with the deepest imports, in the order that the import statements for them are reached. After a top-level...
This method of organizing the rules comes from Constable and Mendler [1985] and Mendler [1988]; it can be made more expressive using the subtyping relation S ⊑ T and dependent function types and parameterized recursions. First, with dependent types we getH¯,u:μX.FX⊢μu;f,y.g∈...

To perform termination assurance, cycles in the grammar using standard techniques to find left recursion are identified. Generally, the GAPAL code blocks themselves will not result in infinite loops and, thus, are known to terminate. However, improper use of a resolution operator may create a ...
After tessellation, the engine traverses the Binary Triangle Tree created in the previous step. Leaf nodes in the tree represent triangles which need to be output to the graphics pipeline. The triangle coordinates are calculated on the fly during the traversal. ...
