WordPress has two similar translation functions __() and _x(). The function _x() does the same thing as the function __() except the _x() function allows you to define a context for the translation (with the $context parameter). This is helpful when you have a string that could be two different words. For example there are two words that are spelled “tear” each with a separate meaning (and separate pronunciation). By including the context you could use both of these words and have them correctly translated based on their $context value.

WordPress JavaScript async defer
When loading JavaScript on a webpage with the “script” tag, there are additional attributes you can add to tell the browser how and when to load the JavaScript (‘async’ and ‘defer’). In WordPress, there is not a native way to add these attributes but this code snippet does the trick.
