  • JS libraries and frameworks such as React, Vue, Svelte, etc.

  • Accessible web development
  • Gravity Forms development


  • $90,000 per year, plus year-end bonus
  • Flexible schedule
  • Unlimited paid time off, with 15-day minimum vacation time
  • Sick/mental health days encouraged
  • Reproductive health care travel reimbursement up to $4,000

In the code below, we want $text to equal 'second param'. It’s not working. In a sentence, why not?
add_filter( 'this_has_two_parameters', function( $first, $second ) {
	return $second;
} );

$text = apply_filters( 'this_has_two_parameters', 'first param', 'second param' );
