Can't export when enumerable is "!0" #64
Description
Input File:
Object.defineProperty(exports, 'a', {
enumerable: true,
value: 'a'
});
Object.defineProperty(exports, 'b', {
enumerable: !0,
value: 'b'
});Expected Result: ["a", "b"]
Actual Result: ["a"]
We can get this case when we use uglifyjs to minify our source code.
The Error is occured in https://github.com/guybedford/cjs-module-lexer/blob/a96e7b52b99d39fee25d69f356905161d14a15ed/lexer.js#L370
Here is a simple solution:
if (source.startsWith('true', pos)) {
pos += 4;
} else if (source.startsWith('!0', pos)) {
pos += 2;
} else {
break;
}
