强制分号的位置
此规则报告的一些问题可通过 --fix 命令行 选项自动修复
This rule was deprecated in ESLint v8.53.0. It will be removed in v11.0.0. Please use the corresponding rule in @stylistic/eslint-plugin.
通常，分号位于行末。然而，在无分号风格中，分号位于行首。此规则强制分号位于配置的位置。
🌐 Generally, semicolons are at the end of lines. However, in semicolon-less style, semicolons are at the beginning of lines. This rule enforces that semicolons are at the configured location.

该规则有一个选项。
🌐 This rule has an option.
{
"semi-style": ["error", "last"],

/*eslint semi-style: ["error", "last"]*/
foo()
;[1, 2, 3].forEach(bar)

; ++i
) {
foo()
}
class C {
static {
foo()
;bar()
