Breaking a string into chunks of defined length and removing spaces using JavaScript
Problem
We are required to write a JavaScript function that takes in a string sentence that might contain spaces as the first argument and a number as the second argument.
Our function should first remove all the spaces from the string and then break the string into a number of chunks specified by the second argument.
All the string chunks should have the same length with an exception of last chunk, which might, in some cases, have a different length.
Example
Following is the code −
const num = 5;
const str = 'This is an example string';
const splitString = (str = '', num = 1) => {
str = str.replace(/\s/g,'');
const arr = [];
for(let i = 0; i < str.length; i += num){
arr.push(str.slice(i,i + num));
};
return arr;
};
console.log(splitString(str, num));Output
[ 'Thisi', 'sanex', 'ample', 'strin', 'g' ]
