unicorn/no-array-sort Suspicious ​
What it does ​
Prefer using Array#toSorted()
over Array#sort()
.
Why is this bad? ​
Array#sort()
modifies the original array in place, which can lead to unintended side effects—especially when the original array is used elsewhere in the code.
Examples ​
Examples of incorrect code for this rule:
js
const sorted = [...array].sort();
Examples of correct code for this rule:
js
const sorted = [...array].toSorted();
Options ​
allowExpressionStatement ​
{ type: boolean, default: true }
This rule allows array.sort()
as an expression statement by default, Pass allowExpressionStatement: false to forbid Array#sort()
even if it's an expression statement.
Examples of incorrect code for this rule with the { "allowExpressionStatement": false }
option:
js
array.sort();
