isCurrentYear

Test if a value is the current year.

Usage

var isCurrentYear = require( '@stdlib/assert/is-current-year' );

isCurrentYear( value )

Tests if a value is either an integer equal to the current year or a Date object representing the current year.

var currentYear = require( '@stdlib/time/current-year' );

var bool = isCurrentYear( currentYear() );
// returns true

bool = isCurrentYear( 2021 );
// returns false

Examples

var currentYear = require( '@stdlib/time/current-year' );
var isCurrentYear = require( '@stdlib/assert/is-current-year' );

var bool = isCurrentYear( new Date() );
// returns true

bool = isCurrentYear( currentYear() );
// returns true

bool = isCurrentYear( 2021 );
// returns false

bool = isCurrentYear( null );
// returns false

CLI

Usage

Usage: is-current-year [options] [<year>]

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 $'1998\n1999' | is-current-year --split /\r?\n/
    
    # Escaped...
    $ echo -n $'1998\n1999' | is-current-year --split /\\r?\\n/
    
  • The implementation ignores trailing delimiters.

Examples

$ is-current-year 2011
false

To use as a standard stream,

$ echo -n 1914 | is-current-year
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 '2001\t2002' | is-current-year --split '\t'
false
false
