Regex to replace exact matching string

Question

I want a regex expression to replace the string which exactly matches it.

For e.g : - var a = '@test @te @world @dimension'

I need to replace '@te' .

Since '@te' exists in @test as well so Replace statement is replacing the @test in my case.

So could anyone please let me know how can this be done.

Just the exact matching string needs to be replaced.

This should work for you:

/\@te\b/

Try this

var a = '@test @te @world @dimension';
var b = a.replace(/@te /, '');

Exactly what isn't a regular expression?

I think this is what OP wants. OP has tagged javascript and asked help to replace desired string with his choice so I gave this example.
