Problem
We are required to write a JavaScript function that takes in an array of string that contains weights with three units: grams (G), kilo-grams (KG) and tonnes (T). Our function should sort the array into order of weight from light to heavy.
We are required to write a JavaScript function that takes in an array of string that contains weights with three units: grams (G), kilo-grams (KG) and tonnes (T). Our function should sort the array into order of weight from light to heavy.
Example
Following is the code −
const arr = ['1456G', '1KG', '.5T', '.005T', '78645G', '23KG']; const arrangeWeights = (arr = []) => { const sorted=(w)=>{ if(w.slice(-2) === 'KG'){ return +w.slice(0,-2) * 1; }else if(w.slice(-1)==='T'){ return +w.slice(0, -1)*1000 }else{ return +w.slice(0, -1)*0.001; }; }; return arr.sort((a, b) => sorted(a) - sorted(b)); }; console.log(arrangeWeights(arr));
Output
[ '1KG', '1456G', '.005T', '23KG', '78645G', '.5T' ]
