Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:

### Example 1
This code
{% codeblock lang:js example %}
str_split('Hello Friend', 3);

['Hel', 'lo ', 'Fri', 'end']
{% endcodeblock %}
