<div class="desc"><p>Returns the length of its argument: the element count of a slice, or the byte length of a string. Use it to iterate a slice with <code>for index in 0 .. len(items)</code>, to check whether a collection is empty, or to compute string slice bounds such as trimming a suffix. It reads the current length, so after you <code>push</code> onto a slice the value it returns grows accordingly. For strings, note it counts bytes, not visual characters.</p></div>
