Abstract—Limited memory in mobile devices presents the bottleneck to execution speed. Abstract Syntax Tree (AST) could be a better option for mobile codes as it is compiled only once. Hence, to improve the execution speed of a mobile device, AST node should be designed in such a way that it would consume less memory and improve the execution speed. In this paper, we implement AST node optimization technique for a set of frequently used operators and statements on a JavaScript compiler, such as Identifiers, Function-calls, Dot-operator and If-then-else. The desired optimization is justified by experimental results.
