How can I remove the last char using JavaScript

[Lord]

I have a sentence on my project build in JavaScript (for example) like this:

"Hello! Welcome Lord to ABC Companys"

As you can see the last word should be "Company" (without 's'). After the project has been completed, I noticed this on the welcome screen. I want to correct this mistake done by my developer who is out of the city for company work. But I don't know much of coding. How can I remove the last char (i.e. 's') using JavaScript?

Its simple. The basic idea is assign the string to a variable. Using this string variable, create a new variable with value same as the previous variable but removing the last character. Now call this variable on your welcome screen.

var str1 = 'Hello! Welcome Lord to ABC Companys';
var str2 = str1.substring(0, str1.length-1);
alert(str2);

There is yet another way to achieve what you want. Use Left function. The code goes like this:

YourString = Left(YourString, Len(YourString) - 1)

This is similar to the previous one but replaces the three code line. Also since it overwrites the original string variable, there is no overload of calling the first variable, executing the code and then finally displaying the result. Thus reducing the time consumed to run your project.

There are two ways to get this. First using substring function and second using replaceAll.

substring syntax

substring(from, [to]) - Returns the characters in a string between "from" and "to" indexes. Using "to" is optional, and can be omitted to get the string till the end.

replaceAll syntax

function replaceAll(yourstring, from, to)
{
var newStr = yourstring.indexOf(from);
while (newStr > -1) {
yourstring = yourstring.replace(from, to);
newStr = yourstring.indexOf(from);
}
return yourstring;
}
