To reverse a array functionally in JavaScript, we'll leverage the spread operator and themap()function: // Preserves original arrayletnumArrReversed = numArr.map(numArr.pop, [...numArr]);// Doesn't preserve original arrayletstrArrReversed = [...strArr].map(strArr.pop, strArr); ...
JavaScript Reverse String Example let str = 'JavaScript'; let splitString = str.split('') let reverseArray = splitString.reverse(); let newString = reverseArray.join(''); console.log(newString); // output: tpircSavaJ How to reverse a string with a for loop in JavaScript?
The simplest way to reverse a string in JavaScript is to split a string into an array,reverse()it andjoin()it back into a string. With ES6, this can be shortened and simplified down to: letstring ="!onaiP"string = [...string].reverse().join("");console.log(string);// "Piano!
在本例中,我们将把 concat() 中的参数连接到数组 a 中: var a = [1,2,3]; document.write(a.concat(4,5)); 输出: 1,2,3,4,5 2、join() 把数组的所有元素放入一个字符串。 join() 方法用于把数组中的所有元素放入一个字符串。 元素是通过指定的分隔符进行分隔的。 例子1 var fruits = [...
