How to get remaining string after substring deletion in JavaScript?

Question

I have a string 123456789.

My aim is to get 1236789 after deleting 45. I used slice method to delete the string 45.

 var x = 123456789;
 res = x.slice(4, 5); //my output is 45

I need the output to be 1236789

Any help would be appreciated.

Slice before, slice after, and concatenate the resulting strings or replace the 45 with an empty string:

var x = "123456789"
var res1 = x.slice(0, 3) + x.slice(5)

console.log(res1)

var res2 = x.replace('45', '')
console.log(res2)

try replace/2.

"123456789".replace("45", "") /** 1236789 */

Or, if your input is an integer and you need and integer as an outcome,

var a = 123456789;  
parseInt(a.toString().replace("45", ""))

You can so this:

var x = "123456789";
var result = x.substr(0, 3) + x.substr(5);
console.log(result)
