What is the best way to check if a JavaScript String includes the pattern:
"@aRandomString.temp"
I need to verify if the String includes an @ character followed by any string and finally ".temp".
Thank you

This single line of code can efficiently accomplish the task by utilizing regex#test(Strng):
var s = 'foo bar @aRandomString.temp baz';
found = /@.*?\.temp/i.test(s); // true
Utilize the method indexOf to search for a specific string within another string.
var text = "@exampleString.sample";
var atSymbol = text.indexOf("@");
var dotTemp = text.indexOf(".sample", atSymbol); // consider atSymbol as starting point, not valid: ".sample @"
if (atSymbol !== -1 && dotTemp !== -1) {
var exampleString = text.substr(atSymbol + 1, dotTemp - atSymbol);
console.log(exampleString); // "exampleString"
}
Give this a shot
let str = "@something.temp";
if (str.includes("@") && str.includes(".temp")) {
}
If you need to find a specific pattern in a string, the match function is your friend. The match function requires a regular expression as input.
function extractString()
{
var str="@someting.temp";
var result=str.match(/@[a-zA-Z]+\.temp/g);
}
