Branch prediction. With a sorted array, the condition data[c] >= 128 is first false for a streak of values, then becomes true for all later values. That's easy to predict. With an unsorted array, you pay for the branching cost.

You can use the substring function: let str = "12345.00"; str = str.substring(0, str.length - 1); console.log(str); This is the accepted answer, but as per the conversations below, the slice syntax is much clearer: let str = "12345.00"; str = str.slice(0, -1); console.log(str); Neither method mutates
<p>You can use the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/substring" rel="noreferrer">substring</a> function:</p> <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false" data-babel-preset-react="false" data-babel-preset-ts...

some_list[-1] is the shortest and most Pythonic. In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)] , which gives you the first element. ...
