Expected a 'for-of' loop instead of a 'for' loop with this simple iteration Open
for (let i = 0; i < csg.polygons.length; i++) {
- Read upRead up
- Exclude checks
Rule: prefer-for-of
Recommends a 'for-of' loop over a standard 'for' loop if the index is only used to access the array being iterated.
Rationale
A for(... of ...) loop is easier to implement and read when the index is not needed.
Config
Not configurable.
Examples
"prefer-for-of": true

Forbidden bitwise operation Open
const triCount = (index.length / 3) | 0;
- Read upRead up
- Exclude checks
Rule: no-bitwise
Disallows bitwise operators.
Specifically, the following bitwise operators are banned:
&
, &=
, |
, |=
,
^
, ^=
, <<
, <<=
,
>>
, >>=
, >>>
, >>>=
, and ~
.
This rule does not ban the use of &
and |
for intersection and union types.
Rationale
Bitwise operators are often typos - for example bool1 & bool2
instead of bool1 && bool2
.
They also can be an indicator of overly clever code which decreases maintainability.
Config
Not configurable.
Examples
"no-bitwise": true

Multiple variable declarations in the same statement are forbidden Open

- Read upRead up
- Exclude checks
Rule: one-variable-per-declaration
Disallows multiple variable definitions in the same declaration statement.
Config
One argument may be optionally provided:
-
ignore-for-loop
allows multiple variable definitions in a for loop declaration.

unused expression, expected an assignment or function call Open
colors && geom.setAttribute('color', new BufferAttribute(colors.array, 3));
- Read upRead up
- Exclude checks
Rule: no-unused-expression
Disallows unused expression statements.
Unused expressions are expression statements which are not assignments or function calls (and thus usually no-ops).
Rationale
Detects potential errors where an assignment or function call was intended.
Config
Three arguments may be optionally provided:
-
allow-fast-null-checks
allows to use logical operators to perform fast null checks and perform method or function calls for side effects (e.g.e && e.preventDefault()
). -
allow-new
allows 'new' expressions for side effects (e.g.new ModifyGlobalState();
. -
allow-tagged-template
allows tagged templates for side effects (e.g.this.add\
foo`;`.
