CDATA codes

hi,

in fact we make a lot of contact forms with popup maker,

checking in behind the source code i see following lines :

var wpcf7 = {“api”:{“root”:”http:\/\/test.domain.tld\/wp-json\/”,”namespace”:”contact-form-7\/v1″}};

is that a normal lines or not ,

also is there any chance to move out from index page because it take a lot of time for load the web page
