{% hint style="success" %}
Because fetching a single big file tends to be faster than fetching a lot of tiny ones, web programmers have started using tools that roll their <mark style="color:yellow;">**modules**</mark> back into a <mark style="color:yellow;">**single big file**</mark> before they publish it to the Web. Such tools are called <mark style="color:purple;">**bundlers**</mark>.
