Test if a value is a string in Pascal case.
npm install @stdlib/assert-is-pascalcase-cliWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Test if a value is a string in Pascal case.
To use as a general utility, install the CLI package globally
``bash`
npm install -g @stdlib/assert-is-pascalcase-cli
`text
Usage: is-pascalcase [options] [
Options:
-h, --help Print this message.
-V, --version Print the package version.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
`
- If the split separator is a [regular expression][mdn-regexp], ensure that the split option is either properly escaped or enclosed in quotes.
`bash`
# Not escaped...
$ echo -n $'beEp booP\nFooBar' | is-pascalcase --split /\r?\n/
# Escaped...
$ echo -n $'beEp booP\nFooBar' | is-pascalcase --split /\\r?\\n/
- The implementation ignores trailing delimiters.
`bash`
$ is-pascalcase Beep
true
To use as a [standard stream][standard-streams],
`bash`
$ echo -n 'boop' | is-pascalcase
false
By default, when used as a [standard stream][standard-streams], the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
`bash`
$ echo -n 'beep\tFooBar' | is-pascalcase --split '\t'
false
true
