Regex to replace exact matching string

Question

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

For eg : - 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.

Try this

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