How to check string contains substring in javascript

Question

I have strings as below, I am search text order in all variables but I want to return true for string2 and string3 but for string1 should be false.

var string1 = "orders"
var string2 = "orders/pack"
var string3 = "orders/123"
var str = "order"
console.log(string1.includes(str)); //false 
console.log(string2.includes(str)); //true
console.log(string3.includes(str)); //true

From what I am seeing, all three strings contain the substring order. Is there a typo, or do you want to include some more explanation? — Tim Biegeleisen

from your code snipp logic should be contains the word and should contain (/) in word — programtreasures

You can make check like this:

console.log( string1.includes(str) && (string1 != str) );

(string1 != str) will not work, it is matching order with orders!!

var string1 = "orders"
var string2 = "orders/pack"
var string3 = "orders/123"
var str = "/"
console.log(string1.includes(str)); //false 
console.log(string2.includes(str)); //true
console.log(string3.includes(str)); //true

Why are you not using '/' instead of 'orders'? Any boundations which we dont know?

How is this different to the OP, other than you've appended an "s" to str?

Vinoth Over a year ago

include will check the given string is present or not. here all the string has order which means all the string has order so that only it returned as true for all the result

RobG Over a year ago

The OP doesn't want them all to return true, the first should return false (based on some unspecified criterion).

in my case first case return false only, another case return true
