Divide a string into n equal parts - JavaScript
We are required to write a JavaScript function that takes in a string and a number n (such that n exactly divides the length of string). We need to return an array of string of length n containing n equal parts of the string.
Let’s write the code for this function −
Example
const str = 'this is a sample string'; const num = 5; const divideEqual = (str, num) => { const len = str.length / num; const creds = str.split("").reduce((acc, val) => { let { res, currInd } = acc; if(!res[currInd] || res[currInd].length < len){ res[currInd] = (res[currInd] || "") + val; }else{ res[++currInd] = val; }; return { res, currInd }; }, { res: [], currInd: 0 }); return creds.res; }; console.log(divideEqual(str, num));
Output
Following is the output in the console −
[ 'this ', 'is a ', 'sampl', 'e str', 'ing' ]
