Sometimes, we want to do a Case insensitive replace all with JavaScript string.
In this article, we’ll look at how to do a Case insensitive replace all with JavaScript string.
Do a Case Insensitive Replace All with a JavaScript String
To do a Case insensitive replace all with JavaScript string, we can use a regex to do the replacement.
For instance, we can write:
const str = 'This iS IIS'.replace(/is/ig, 'as');
console.log(str)
We call replace on a string with the i and g flags to search for all instances of 'is' in a case insensitive manner.
And we replace each instance with 'as' .
The i flag lets us search for all instances of the pattern in a case-insensitive manner.
The g flag lets us search for all instances of the regex pattern.
As a result, str is 'Thas as Ias’ .
Conclusion
