{ "linter": { "rules": { "style": { "noSubstr": "error" } } }}¥Description
强制使用 String.slice() 而不是 String.substr() 和 String.substring()。
¥Enforce the use of String.slice() over String.substr() and String.substring().
String.slice() 优于 String.substr() 和 String.substring()，因为它是一种更受欢迎的选项，行为更清晰，并且在数组中具有一致的对应项。
¥String.slice() is preferred over String.substr() and String.substring() because it is a more popular option with clearer behavior,
and it has a consistent counterpart in arrays.
请注意，传递参数时，String.substr、String.substring 和 String.slice 并不相同。有关详细差异，请参阅 MDN 文档：
¥Note that String.substr, String.substring and String.slice are not identical when arguments are passed.
For detailed differences, refer to the MDN documentation:
