isCamelcase

Test if a value is a camelcase string.

Usage

var isCamelcase = require( '@stdlib/assert/is-camelcase' );

isCamelcase( value )

Tests if a value is an camelcase string.

var bool = isCamelcase( 'beepBoop' );
// returns true

bool = isCamelcase( 'beep and Boop' );
// returns false

Notes

The function validates that a value is a string. For all other types, the function returns false.

Examples

var isCamelcase = require( '@stdlib/assert/is-camelcase' );

console.log( isCamelcase( 'beepBoop' ) );
// => true

console.log( isCamelcase( 'beepBoop123' ) );
// => true

console.log( isCamelcase( 'beep Boop' ) );
// => false

console.log( isCamelcase( 'beep' ) );
// => true

console.log( isCamelcase( 'beep boop' ) );
// => false

console.log( isCamelcase( 'b' ) );
// => true

CLI

Usage

Usage: is-camelcase [options] [<string>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --split sep           Delimiter for stdin data. Default: '/\\r?\\n/'.

Notes

If the split separator is a regular expression, ensure that the split option is either properly escaped or enclosed in quotes.

# Not escaped...
$ echo -n $'beEp booP\nFOO' | is-camelcase --split /\r?\n/
# Escaped...
$ echo -n $'beEp booP\nFOO' | is-camelcase --split /\\r?\\n/

The implementation ignores trailing delimiters.

Examples

$ is-camelcase beepBoop
true

To use as a standard stream,

$ echo -n 'beep Boop' | is-camelcase
false

By default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.

$ echo -n 'beepBoop\tbeep_boop' | is-camelcase --split '\t'
true
false
