Pattern: Use of Array#reduce() or Array#reduceRight()
Issue: -
Using Array#reduce() or Array#reduceRight() often results in code that is harder to read and less performant. These methods can usually be replaced with .map, .filter, or a for-of loop for better clarity and performance. The exception is simple number summation, which is allowed by default.
Example of incorrect code:
array.reduce(reducer, initialValue);
array.reduceRight(reducer, initialValue);Example of correct code:
// Using map
const result = array.map(x => x.value);
// Using for-of
let result = 0;
for (const num of numbers) {
result += num;
}
