The first time I interact with JS, and this code caught my eye.

$(document).ready(function(){ fix_spell = function(data) { data.forEach(function(elem) { $('#text_field').val( $('#text_field').val().replace( elem['word'], elem['s'][0] || elem['word'] ) ); });

I understand that there is a replacement for every element on the page, but what is changing?

This line is incomprehensible:

 elem['word'], elem['s'][0] || elem['word']

Thank you in advance for your help)

  • This string is the arguments of the replace function, what to change, and what to change, separated by commas. or not to change (change to the same line) - teran
  • @teran, yes, I understand that, I also understand that the word element is changed to a word or .... this is the catch, what kind of construction is this elem['s'][0] ? - Violofan
  • "for each item on the page" is where is it from? Only for one element with id="text_field" . And the fact where this fix_spell is fix_spell is unknown. - Igor

So it will be clearer:

  $('#text_field').val( $('#text_field').val().replace( elem.word, elem.s[0] || elem.word ) );

or

  if (elem.s[0]) { $('#text_field').val( $('#text_field').val().replace(elem.word, elem.s[0]) ); }
