Convert camel case to sentence case in javascript

The below uses capitalised notation for acronyms; I don't agree with Microsoft's recommendation of capitalising when more than two characters so this expects the whole acronym to be capitalised even if it's at the start of the string (which technically means it's not camel case but it gives sane controllable output), multiple consecutive acronyms can be escaped with _ (e.g. parseDBM_MXL -> Parse DBM XML).

function camelToSentenceCase(str) {
    return str.split(/([A-Z]|\d)/).map((v, i, arr) => {
        // If first block then capitalise 1st letter regardless
        if (!i) return v.charAt(0).toUpperCase() + v.slice(1);
        // Skip empty blocks
        if (!v) return v;
        // Underscore substitution
        if (v === '_') return " ";
        // We have a capital or number
        if (v.length === 1 && v === v.toUpperCase()) {
            const previousCapital = !arr[i-1] || arr[i-1] === '_';
            const nextWord = i+1 < arr.length && arr[i+1] && arr[i+1] !== '_';
            const nextTwoCapitalsOrEndOfString = i+3 > arr.length || !arr[i+1] && !arr[i+3];
            // Insert space
            if (!previousCapital || nextWord) v = " " + v;
            // Start of word or single letter word
            if (nextWord || (!previousCapital && !nextTwoCapitalsOrEndOfString)) v = v.toLowerCase();
        }
        return v;
    }).join("");
}

How to convert string to Title Case in Python?

Why not use title Right from the docs:

>>> "they're bill's friends from the UK".title()
"They'Re Bill'S Friends From The Uk"

If you really wanted PascalCase you can use this:

>>> ''.join(x for x in 'make IT pascal CaSe'.title() if not x.isspace())

How do I convert a string to title case in android?

     /**
     * Function to convert string to title case
     * 
     * @param string - Passed string 
     */
    public static String toTitleCase(String string) {

        // Check if String is null
        if (string == null) {
            
            return null;
        }

        boolean whiteSpace = true;
        
        StringBuilder builder = new StringBuilder(string); // String builder to store string
        final int builderLength = builder.length();

        // Loop through builder
        for (int i = 0; i < builderLength; ++i) {

            char c = builder.charAt(i); // Get character at builders position
            
            if (whiteSpace) {
                
                // Check if character is not white space
                if (!Character.isWhitespace(c)) {
                    
                    // Convert to title case and leave whitespace mode.
                    builder.setCharAt(i, Character.toTitleCase(c));
                    whiteSpace = false;
                }
            } else if (Character.isWhitespace(c)) {
                
                whiteSpace = true; // Set character is white space
            
            } else {
            
                builder.setCharAt(i, Character.toLowerCase(c)); // Set character to lowercase
            }
        }

        return builder.toString(); // Return builders text
    }

Convert string to title case with exceptions for articles (a, an, the..etc)

The Array.includes(String) function returns if the string is a part of the array.

This should work,

for(i = 0; i < splitStr.length; i++) { 
    // Check if our word is a part of the exceptions list
    if(i>0 && exceptions.includes(splitStr[i]))
        // if it's an exception skip the capatilization
        continue;

    splitStr[i] = splitStr[i].charAt(0).toUpperCase() + splitStr[i].substring(1);
}

Credit for i>0 condition goes to @Ringo, i didn't think about that before. He's right that first word should always be capitalized regardless.
