We are required to write a JavaScript function that takes in an array of strings and returns the index of string that is shortest in length.
We will simply use a for loop and persist the index of string which is shortest in length.
Therefore, let’s write the code for this function −
Example
The code for this will be −
const arr = ['this', 'can', 'be', 'some', 'random', 'sentence'];
const findSmallest = arr => {
const creds = arr.reduce((acc, val, index) => {
let { ind, len } = acc;
if(val.length < len){
len = val.length;
ind = index;
};
return { ind, len };
}, {
ind: -1,
len: Infinity
});
return arr[creds['ind']];
};
console.log(findSmallest(arr));Output
The output in the console will be −
be
