1 line of code: How to the get length of the shortest string of an Array

#javascript #webdev #performance #codequality 
    const shortestStringLength = (arr, curr = Infinity) => (arr.forEach(el => { if (el.length < curr) curr = el.length }), curr);
Enter fullscreen mode Exit fullscreen mode

Returns the length of the shortest string entry of an Array of strings.

The repository & npm package

You can find the all the utility functions from this series at github.com/martinkr/onelinecode
The library is also published to npm as @onelinecode for your convenience.

The code and the npm package will be updated every time I publish a new article.

This method is faster both on Firefox (almost 5 times as fast!) and on Chrome

const shortestStringLength = (arr, a=Infinity)=>(arr.forEach(i=>{if (i.length<a) a=i.length}),a)
Enter fullscreen mode Exit fullscreen mode
