JavaScript: Tips of the Day

Sort Number Arrays

JavaScript arrays come with a built-in sort method. This sort method converts the array elements into strings and performs a lexicographical sort on it by default. This can cause issues when sorting number arrays. Hence here is a simple solution to overcome this problem.

[0,10,4,9,123,54,1].sort((a,b) => a-b);
>>> [0, 1, 4, 9, 10, 54, 123]

You are providing a function to compare two elements in the number array to the sort method. This function helps us the receive the correct output.
