Adding a multiple space character's in nodejs using replace method-CodePudding

I have the following variable.

var s = 'Hi Al !'

Which i would like to convert to

'Hi    Al !'

I.E. basically add 4 space characters and hence taught i could do the following:-

var new_var = s.replace('Hi', 'Hi\s\s\s\s');

But the above only gives me the output Hissss Al !, which is not what i want. How do i add 4 space characters to my string ?

I have also tried var new_var = s.replace('Hi', 'Hi\t');

But the output has about 6-7 spaces.

Just use the space character:

var s = 'Hi Al !'
var new_var = s.replace('Hi', 'Hi    ');
console.log(new_var)

CodePudding user response：

Using \s matches a whitespace char using a regular expression. If you use that in the replacement, it will just be s

If there is a variable number of spaces after Hi, and you want to change that to always have 4 spaces, you can match 1 or more whitespace chars and use 4 spaces in the replacement.

var s = 'Hi              Al !';
var new_var = s.replace(/Hi\s /, 'Hi    ');
console.log(new_var)
