The video tutorial explains how to create a JavaScript function called 'title capitalize' that takes a string as an argument and returns the string with the first letter of each word capitalized. The instructor demonstrates various string manipulation techniques, including converting strings to lowercase, splitting strings into arrays, and using loops to iterate over words. The tutorial also covers using methods like charAt and slice to capitalize the first letter of each word and join to return the final formatted string.
