<p>You know what's one of the worst function names ever? <code>sleep()</code>.</p>
|
||
|
|
<p>Sleep for how long? It is seconds or milliseconds?</p>
|
||
|
|
<span id="continue-reading"></span>
|
||
|
|
<p>Now let me ask you this: Would it clearer if the function was called
|
||
|
|
<code>sleepForMs()</code>? Would you understand that the function would make the
|
||
|
|
application sleep for a number of milliseconds?</p>
|
||
|
|
<p>What about <code>sleepForSecs()</code>? Do you understand that this will force your
|
||
|
|
application to sleep for a number of seconds?</p>
|
||
|
|
<p>What if, instead of using the function name, you could use <code>sleep("10s")</code>? Does
|
||
|
|
it make clear that you want it to sleep for 10 seconds?</p>
|
||
|
|
<p>That's why adding units to the function or parameters make sense. It removes
|
||
|
|
the ambiguity of what it means and doesn't rely on some specialized IDE/Editor
|
||
|
|
that display the parameter names.</p>
