ESLintDisallow Self Assignment (no-self-assign)
Self assignments have no effect, so probably those are an error due to incomplete refactoring. Those indicate that what you should do is still remaining.
foo = foo;
[bar, baz] = [bar, qiz];
Rule Details
This rule is aimed at eliminating self assignments.
Examples of incorrect code for this rule:
/*eslint no-self-assign: "error"*/
foo = foo;
[a, b] = [a, b];
[a, ...b] = [x, ...b];
({a, b} = {a, x});
Examples of correct code for this rule:
/*eslint no-self-assign: "error"*/
foo = bar;
[a, b] = [b, a];
// This pattern is warned by the `no-use-before-define` rule.
let foo = foo;
// The default values have an effect.
[foo = 1] = [foo];
When Not To Use It
If you don’t want to notify about self assignments, then it’s safe to disable this rule.
Version
This rule was introduced in ESLint 2.0.0-rc.0.
