We are required to write a JavaScript function that checks whether a sentence is smooth or not. A sentence is smooth when the first letter of each word in the sentence is same as the last letter of its preceding word.
Example
Following is the code −
const str = 'this stringt tries sto obe esmooth'; const str2 = 'this string is not smooth'; const isSmooth = str => { const strArr = str.split(' '); for(let i = 0; i < strArr.length; i++){ if(!strArr[i+1] || strArr[i][strArr[i].length -1] === strArr[i+1] [0]){ continue; }; return false; }; return true; }; console.log(isSmooth(str)); console.log(isSmooth(str2))
Output
Following is the output in the console −
true false
