this wont work because
var market_data_text_1 = "<?php the_field('market_data_1_text') ; ?>";
this works because backticks allows multiline, it may not work on all browsers
In EcmaScript 6, you are able to use backticks for Template Strings, known in
the spec as a NoSubstitutionTemplate:
var htmlString = `Say hello to
multi-line
strings!`;
OR
var market_data_text_1 = `<?php the_field('market_data_1_text') ; ?>`;
