Handlebars Cookbook - LightnCandy option: FLAG

compile to echo 'a', $b, 'c'; to improve performance. This will slow down rendering when the template and data are simple, but will improve 5% ~ 10% when the data is big and looping in the template.

compile to 'a' . $b . 'c' when do not use FLAG_ECHO

Used option: FLAG_JSTRUE

Data:

NULL

Template:

A{{{foo}}}C

Result:

use \LightnCandy\Runtime as LR;return function ($in = null, $options = null) {
    $helpers = array();
    $partials = array();
    $cx = array(
        'flags' => array(
