I'm using the following code to search sub string in a string

mystring.search(new RegExp(substring, 'i'))

Reason why I am using new RegExp is, I want to search case insensitive. However, when there is a string like

var mystring = '10" stick';

and I want to search 10", the code above does not return any result. It's clearly because of new RegExp and double quote. Is there any particular flag that needs to be passed in new RegExp? I googled a lot but couldn't find any solution. What am I missing?

search returns match position, maybe ur confused by this.
So, try this out,

const myString = '10" stick';

console.log(myString.match(new RegExp('10"', 'i'))[0])
console.log(myString.match(new RegExp('ick', 'i'))[0])
console.log(myString.match(new RegExp('asd"', 'i'))) // non-matching

It returns the match or null if theres non. AND it matches 10" in 10" stick

see String.prototype.search mdn
