Here is the my string
var string = 'Title:(India OR America) OR Keyword:(Education)';
After splitting with "OR" it is showing
["Title:(India", "America)", "Keyword:(Education)"]
But what I need is the below one.
["Title:(India OR America)", "Keyword:(Education)"]
Could anyone please help on how to split the string to get the required result.

To achieve this you'll need to use a negative lookahead to only find the OR string where it's not contained in parentheses. Try this:
var input = 'Title:(India OR America) OR Keyword:(Education)';
var output = input.split(/(?!\(.*)\s?OR\s?(?![^(]*?\))/g);
console.log(output);

Remove First Character of (Original) String in JavaScript [duplicate]

the best way to remove the first char of a given string in javascript

I see this article but it's specific to deleting a character if it's a certain number (0, in that case).
I want to remove the first character from a string no matter what it is.
splice() and shift() won't work because they're specific to arrays:
let string = "stake";
string.splice(0, 1);
console.log(string);
let string = "stake";
string.shift();
console.log(string);
slice() gets the first character but it doesn't remove it from the original string.
let string = "stake";
string.slice(0, 2);
console.log(string);
Is there any other method out there that will remove the first element from a string?

Use substring
let str = "stake";
str = str.substring(1);
console.log(str);

How replace all "/" to "-" in a string using Javascript [duplicate]

How do I replace all occurrences of a string in JavaScript?

Closed 3 years ago.
I have a string like
abcd/123/xyz/345
I want to replace every "/" with "-" using JavaScript.
The result string should be abcd-123-xyz-345
I have tried,
string.replace("/","-")
But it replaces the first "/" character only. The result is abcd-123/xyz/345
And
string.replace("///g","-");
is not working as well.
Is there any solution for this?

You can use Regex. You need to escape using backslash \ before the /.
A backslash that precedes a special character indicates that the next character is not special and should be interpreted literally
var str = 'abcd/123/xyz/345';
let result = str.replace(/\//g,'-');
console.log(result);

Please try this,
var str='abcd/123/xyz/345'
var newstr=str.split('/').join('-');
console.log(newstr)

In javascript how it's possible to replace all occurrence of &,<,> in a string
I tried this
var str="<>&";
str.replace("&","&amp").replace("<","&lt").replace(">","&gt");
but not able to change even first occurrence

The easiest would be to use a regular expression with g flag to replace all instances:
str.replace(/foo/g, "bar")
This will replace all occurrences of foo with bar in the string str. If you just have a string, you can convert it to a RegExp object like this:
var pattern = "foobar",
re = new RegExp(pattern, "g");
