Dec 30, 2012 · As described in the docs: Apply a function against an accumulator and each value of the array (from left-to-right) as to reduce it to a single value.

Aug 6, 2019 · 63. If you want the accumulator value to be indexable by string, Record<string, string> should do the trick. You can pass this as the type argument to reduce. [key: string]: number; small: 576, medium: 768, large: 992, extra: 1200. acc[cur] = `(min-width: ${size[cur]}px)`;
