TIL startWith

POSTED ON:

TAGS: mdn javascript string

Getting a boolean result of true or false, depending on if the string startsWith a specific substring.

How it works: 

//startswith
let str = 'To be, or not to be, that is the question.'

console.log(str.startsWith('To be'))          // true
console.log(str.startsWith('not to be'))      // false
console.log(str.startsWith('not to be', 10))  // true

I was looking at ripping string apart by spaces (using the String.prototype.split method), then found this other neat method to do string comparison.
