Function to find the length of the second smallest word in a string in JavaScript
We are required to write a JavaScript function that takes in a string sentence as first and the only argument. And the function should return the length of the second smallest word from the string.
For example: If the string is −
const str = 'This is a sample string';
Then the output should be 2.
Therefore, let’s write the code for this function −
Example
The code for this will be −
const str = 'This is a sample string';
const secondSmallest = str => {
const strArr = str.split(' ');
if(strArr.length < 2){
return false;
}
for(let i = 0; i < strArr.length; i++){
strArr[i] = strArr[i].length;
};
strArr.sort((a, b) => a - b);
return strArr[1];
};
console.log(secondSmallest(str));Output
The output in the console will be −
