This function is intended as a potential performance optimization. In V8, for example, even if two objects share common properties, if those properties were added in different orders or if one object has additional properties not shared by the other object, then those objects will have different \"hidden\" classes. If a function is provided many objects having different \"shapes\", some JavaScript VMs (e.g., V8) will consider the function \"megamorphic\" and fail to perform various runtime optimizations.

- -### Notes - -- If the split separator is a [regular expression][mdn-regexp], ensure that the `split` option is properly **escaped**. - - ```bash - # Not escaped... - $ echo -n $'1\n2\n3\n' | sparkline --split /\r?\n/ - - # Escaped... - $ echo -n $'1\n2\n3\n' | sparkline --split /\\r?\\n/ - ``` - -

- -### Notes - -- If the split separator is a [regular expression][mdn-regexp], ensure that the `split` option is properly **escaped**. - - ```bash - # Not escaped... - $ echo -n $'1\n2\n3\n' | sparkline-column --split /\r?\n/ - - # Escaped... - $ echo -n $'1\n2\n3\n' | sparkline-column --split /\\r?\\n/ - ``` - -

- -### Usage - -```text -Usage: sparkline-updown [options] ... - -Options: - - -h, --help Print this message. - -V, --version Print the package version. - --split sep Separator used to split stdin data. Default: /\\r?\\n/. -``` - -
- - - -
- -### Notes - -- If the split separator is a [regular expression][mdn-regexp], ensure that the `split` option is properly **escaped**. - - ```bash - # Not escaped... - $ echo -n $'1\n2\n3\n' | sparkline-updown --split /\r?\n/ - - # Escaped... - $ echo -n $'1\n2\n3\n' | sparkline-updown --split /\\r?\\n/ - ``` - -
- - - -
- -### Examples - -```bash -$ sparkline-updown -- -1 1 1 1 1 -1 -1 1 -↓↑↑↑↑↓↓↑ -``` - -```bash -$ echo -n $'-1\n1\n1\n1\n1\n-1\n-1\n1\n' | sparkline-updown -↓↑↑↑↑↓↓↑ -``` - -
