Finding average word length of sentences - JavaScript
We are required to write a JavaScript function that takes in a string of strings joined by whitespaces. The function should calculate and return the average length of all the words present in the string rounded to two decimal places
Example
Following is the code −
const str = 'This sentence will be used to calculate average word length';
const averageWordLength = str => {
if(!str.includes(' ')){
return str.length;
};
const { length: strLen } = str;
const { length: numWords } = str.split(' ');
const average = (strLen - numWords + 1) / numWords;
return average.toFixed(2);
};
console.log(averageWordLength(str));
console.log(averageWordLength('test test'));Output
Following is the output in the console −
