unicorn/prefer-native-coercion-functions Pedantic ​
What it does ​
Prefers built in functions, over custom ones with the same functionality.
Why is this bad? ​
If a function is equivalent to String
, Number
, BigInt
, Boolean
, or Symbol
, you should use the built-in one directly. Wrapping the built-in in a function is moot.
Examples ​
Examples of incorrect code for this rule:
javascript
const foo = (v) => String(v);
foo(1);
const foo = (v) => Number(v);
array.some((v) => /* comment */ v);
Examples of correct code for this rule:
javascript
String(1);
Number(1);
array.some(Boolean);
