2017-03-05handle variable declaration within catch blocks (#1546)...accounts for IE8- scopingAlex Lam S.L
2017-03-03properly cover all cases of for-in loop variables (#1536)Alex Lam S.L
2017-03-03fix reference marking in for-in loops (#1535)...fixes #1533Alex Lam S.L
2017-03-02fix corner cases in `reduce_vars` (#1524)...Avoid variable substitution in the following cases: - use of variable before declaration - declaration within conditional code blocks - declaration within loop body fixes #1518 fixes #1525Alex Lam S.L
2017-02-26consolidate `evaluate` & `reduce_vars` (#1505)...- improve marking efficiency - apply smarter `const` replacement to `var` fixes #1501Alex Lam S.L
2017-02-21improve reduce_vars and fix a bug...- update modified flag between compress() passes - support IIFE arguments - fix corner case with multiple definitions closes #1473 alexlamsl
2017-01-26optimise binary operands with evaluate() (#1427)...- remove call to evaluate() in is_constant() and let nested optimize() does its job instead - reject RegExp in is_constant() and remove special case logic under collapse_vars - operands to conditionals optimisation are now always evaluate()-ed - throw error in constant_value() instead of returning undefined to catch possible bugs, similar to make_node_from_constant() - optimise binary boolean operators under `evaluate` instead of `conditionals`Alex Lam S.L
2017-01-26augment evaluate to extract within objects (#1425)...- gated by `unsafe` - replaces previous optimisation specific to String.length - "123"[0] => 1 - [1, 2, 3][0] => 1 - [1, 2, 3].length => 3 - does not apply to objects with overridden prototype functionsAlex Lam S.L
