In TypeScript, we can use the for-loops to iterate through the iterable objects such asarray,map,set,string,arguments objectand so on. This article explores the TypeScriptfor-loop, and its syntax, providing code examples, and explaining its various components. TypeScript supports 3 types of f...
for循环中的分号将三个不同的表达式相互分隔开来:“variable initialization”语句、“stop condition”表达式和"post-iteration“表达式(我只是在这里编名称,但它们符合它们的用途)。 所以,在这行代码中: for (let count = 0;; count++) 把两个分号放在那里,基本上就是说没有中间表达式,也就是说这个for-loop没...
For example, this syntax has also been used with special loaders in bundlers to load CSS or other assets. Your bundler might be configured in such a way where you can include specific .css files by writing something like the following: Copy import "./button-component.css"; export function ...
