Problem
We are required to write a JavaScript function that takes in a camelCase string, str as the first and the only argument.
Our function should construct and return a new string that splits the input string using a space between words.
For example, if the input to the function is −
Input
const str = 'thisIsACamelCasedString';
Output
const output = 'this Is A Camel Cased String';
Example
Following is the code −
const str = 'thisIsACamelCasedString'; const breakCamelCase = (str = '') => { const isUpper = (char = '') => char.toLowerCase() !== char.toUpperCase() && char === char.toUpperCase(); let res = ''; const { length: len } = str; for(let i = 0; i < len; i++){ const el = str[i]; if(isUpper(el) && i !== 0){ res += ` ${el}`; continue; }; res += el; }; return res; }; console.log(breakCamelCase(str));
Output
this Is A Camel Cased String
