Splitting a string into parts in 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) and we need to return an array of string of length n containing n equal parts of the string.
Example
The code for this will be −
const str = 'we will be splitting this string into parts';
const num = 6;
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
The output in the console −
[ 'we will ', 'be split', 'ting thi', 's string', ' into pa', 'rts' ]
