let string = "Hi! Recently India celebrated its Independence Day."

// If we want to know whether a string starts with a particular word or not, 
// we can use ^ symbol in the beginning of the word to check it.

let pattern = /^H/
// ^ is the symbol for 'start of the string'
// by default the matches are case sensitive
// this means that it will be differentiate between 'H' 
// and 'h'
console.log(pattern.test(string)) // true

let patternNew = /^h/i
// i is the symbol for 'case insensitive'
// even though the string starts with 'H' and not 'h'
// the pattern will still match
console.log(patternNew.test(string)) // true
