Find Longest Common Prefix of Array in JavaScript | Learn JavaScript & Algorithms

Find longest common prefix of array in javascript. Write a function that finds the longest common prefix of 'an array of strings' in javascript. One way is to use a while loop to reduce the length of the prefix until it is an empty string or a prefix that is common to all the strings in the array. Define a function which takes in 'an array of strings' as an input. Check if the input is an empty array, if so, return an empty string. Check if given array has only one element, if so, return that element. Assign the first element of given array to a variable. I used variable named as 'prefix'. Use a for loop to iterate through the given array starting from the second element. Inside the loop, use a while loop to continuously shorten the prefix until it is either an empty string or a common prefix shared by all elements in given array. Inside while loop, use the indexOf method to check if prefix is a prefix of the current element. If it's not, shorten the prefix by one character from the end using the substring method. If the prefix becomes an empty string, return an empty string. After the for loop ends, return the prefix. Call the function with array of strings and the result will be returned. So this is how we can find the longest common prefix of 'an array of strings' in javascript.
