Technically not part of ES5, but commonly used code exists in the wild.
|
|
Previous fiix for #1052 perturbs declaration order of functions which leads to incorrect behaviour under "use strict".

As this is not part of ES5.
|
|
fixes #1922
|
|
- preserve (re)assignment to `const` for runtime error
- suppress `cascade` on `const`, as runtime behaviour is ill-defined
|
|
Travis has gone a lot slower recently, and most test failures are due to time-out on this particular test.
|
|
|
|
fixes #1887
|
|
Have `minify()` return `Error` in `result.error` rather than throwing it.
|
|
Re-order `AST_Binary` properties to make dump more readable.

|
|
Only need to avoid `var` within the initialisation block.

|
|
fixes #1830

|
Perform the same cascaded scanning within `var` statement as we do on array of statements.

|
fixes #1825

|
fixes #27
|
|
- remove overlap in functionality of singular, consecutive reference of constant value
- remove workarounds for previous bugs in `lib/scope.js`
- distribute recursive `collapse_single_use_vars()` calls to their respective `OPT(AST_Node)`
- enable collapsing of variables within a single `AST_Definitions`
|
|
`var a=1;a=2;x(a)` => `x(2)`
fix pre-existing issues
- reference counting on assignment
- walking of anonymous functions
- chained assignment
|
|
|
|
Side effects of `&&` and `||` have not mattered until #1814, which takes assignment expressions into account.
|
|
These are surprisingly common, as people reuse the same variable name within loops or switch branches.
|
|
Possible partial execution due to exceptions.
|
|
- allow immediate assignment after declaration of variable
- relax modification rule for immutable value
- fix order of visit for TreeWalker
- remove extraneous code
|
|
- let `collapse_vars` take care of value containing any symbols
- improve overhead accounting
