Powershell string variable substitution

Question

I am quite familiar with bash's ability to substitute parts of strings in a regex-ish fashion using braces. Eg:

a = "Hello, World!"
echo "${a/World/Nancy}"

The above will print "Hello, Nancy!" Does powershell have the ability to do substring-subtitution in this way, or is there an equivalent alternative?

Answer 1

The -replace operator (supports regex):

$a = "Hello, World!"
$a -replace "World","Nancy"
