如何在JavaScript中更改字符串中的单个字符

Question

I have a variable which contains the following string

placeholder = "<strong>Total Damage:</strong> $70,000.00"

Now, I am trying to replace Dollor sign($) with pound sign(£). Any idea how this can be done?

I don't know javascript, still trying to learn. now the solution seems so simple, I feel embarrassed now. Sorry for bothering everyone with such silly question :(
