to prevent the `require`, `exports` and `$` names from being changed.
### Mangling property names (`--mangle-props`)
**Note:** this will probably break your code. Mangling property names is a
separate step, different from variable name mangling. Pass
`--mangle-props`. It will mangle all properties that are seen in some
object literal, or that are assigned to. For example:
```js
var x = {
foo: 1
};
x.bar = 2;
x["baz"] = 3;
x[condition ? "moo" : "boo"] = 4;
console.log(x.something());
```
In the above code, `foo`, `bar`, `baz`, `moo` and `boo` will be replaced
with single characters, while `something()` will be left as is.
In order for this to be of any use, we should avoid mangling standard JS
names. For instance, if your code would contain `x.length = 10`, then
`length` becomes a candidate for mangling and it will be mangled throughout
the code, regardless if it's being used as part of your own objects or
accessing an array's length. To avoid that, you can use `--reserved-file`
to pass a filename that should contain the names to be excluded from
mangling. This file can be used both for excluding variable names and
property names. It could look like this, for example:
```js
{
"vars": [ "define", "require", ... ],
"props": [ "length", "prototype", ... ]
}
```
`--reserved-file` can be an array of file names (either a single
comma-separated argument, or you can pass multiple `--reserved-file`
arguments) — in this case it will exclude names from all those files.
A default exclusion file is provided in `tools/domprops.json` which should
cover most standard JS and DOM properties defined in various browsers. Pass
`--reserve-domprops` to read that in.
You can also use a regular expression to define which property names should be
mangled. For example, `--mangle-regex="/^_/"` will only mangle property names
that start with an underscore.
When you compress multiple files using this option, in order for them to
work together in the end we need to ensure somehow that one property gets
mangled to the same name in all of them. For this, pass `--name-cache
filename.json` and UglifyJS will maintain these mappings in a file which can
then be reused. It should be initially empty. Example:
```
rm -f /tmp/cache.json # start fresh
uglifyjs file1.js file2.js --mangle-props --name-cache /tmp/cache.json -o part1.js
uglifyjs file3.js file4.js --mangle-props --name-cache /tmp/cache.json -o part2.js
```
Now, `part1.js` and `part2.js` will be consistent with each other in terms
of mangled property names.
Using the name cache is not necessary if you compress all your files in a
single call to UglifyJS.

If your input source map is not in a file, you can pass it in as an object
using the `inSourceMap` argument:
```javascript
var result = UglifyJS.minify("compiled.js", {
inSourceMap: JSON.parse(my_source_map_string),
outSourceMap: "minified.js.map"
});
```
The `inSourceMap` is only used if you also request `outSourceMap` (it makes
no sense otherwise).
