As an example, if Jason was riding the roller coaster (and when isn’t he), your goal would be to change his cell from["Jason", "Millhouse"]to just"Jason Millhouse". Notice that an array goes in to the function you will build, but a string comes out. varpassengers = [ ["Thomas"...
You can iterate through the Map elements using thefor...ofloop orforEach()method. The elements are accessed in the insertion order. For example, letmap1 =newMap(); map1.set('name','Jack'); map1.set('age','27');// looping through Mapfor(let[key, value]ofmap1) {console.log(ke...
JavaScript 支持不同类型的循环: for- 循环代码块一定的次数 for/in- 循环遍历对象的属性 while- 当指定的条件为 true 时循环指定的代码块 do/while- 同样当指定的条件为 true 时循环指定的代码块 For 循环 for 循环是您在希望创建循环时常会用到的工具。
