semi-style

The --fix option on the command line can automatically fix some of the problems reported by this rule.

Enforces location of semicolons.

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.

Rule Details

This rule reports line terminators around semicolons.

This rule has an option.

{
    "semi-style": ["error", "last"],
}

"last" (Default) enforces that semicolons are at the end of statements.
"first" enforces that semicolons are at the beginning of statements. Semicolons of for loop heads (for(a;b;c){}) should be at the end of lines even if you use this option.

Examples of incorrect code for this rule with "last" option:

/*eslint semi-style: ["error", "last"]*/

foo()
;[1, 2, 3].forEach(bar)

for (
    var i = 0
    ; i < 10
    ; ++i
) {
    foo()
}

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

Examples of correct code for this rule with "last" option:

/*eslint semi-style: ["error", "last"]*/

foo();
[1, 2, 3].forEach(bar)

for (
    var i = 0;
    i < 10;
    ++i
) {
    foo()
}

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

Examples of incorrect code for this rule with "first" option:

/*eslint semi-style: ["error", "first"]*/

foo();
[1, 2, 3].forEach(bar)

for (
    var i = 0
    ; i < 10
    ; ++i
) {
    foo()
}

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

Examples of correct code for this rule with "first" option:

/*eslint semi-style: ["error", "first"]*/

foo()
