Formatting, methods and string operations

String formatting

JavaScript natively doesn't support camel case conversion and handwriting format conversion

example: MatErNal MortalIty Rate should be

Camel case

Maternal Mortality Rate. We use a custom implementation for this:

function toCamelCase(str) {
  var final_str = str.replace(/\w\S*/g, function (txt) {
    return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
  })
  return final_str
}

Handwriting format

Maternal mortality rate

This is a common utility in multiple BMGF projects (Gender, NHRR, UP TSU). I'm assuming other projects might be using this as well.

function slug(text) {
  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/[^\w\\-]+/g, '')      // Remove all non-word chars
    .replace(/\\-\\-+/g, '-')       // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '');            // Trim - from end of text
}

Slugify

Slufiy is useful to remove any special characters from a phrase. Jammu & Kashmir becomes jammu_kashmir, Andaman and nicobar islands becomes andaman_and_nicobar_islands
