A very good W3school tutorial can be found here.

Javascript – is there a way to avoid removing line breaks while removing extra spaces from a text file?

for example i am using :

string.replace(/s+/g, " ").trim();  // here string being my string name

it replaces all extra spaces with a single space along with line breaks as well.
But i want the line breaks to stay as they are while the extra spaces in a line to be replaced with a single space

    You could use the following negative character class trick here:

    string.replace(/[^Sn]/g, " ").trim();

    The pattern [^Sn] matches:

    • Not S, which is equivalent to s (what you currently have)
    • But also not n, which spares newlines from being replaced
