Can someone please share the most efficient method for verifying if a string in TypeScript contains a particular subString or part of a subString?
For instance, say I have a string path: "home/jobs/AddJobs", and I need to determine if it matches or includes the substring: "home/jobs"
Is there a way to achieve this using Angular 6 in typescript?
When it comes to this question, there are both a traditional and modern perspective:
const route = 'home/jobs/AddJobs';
// Traditional Approach
if (route.indexOf('home/jobs') > -1) {
console.log('The substring is found!');
}
// Modern Approach
if (route.includes('home/jobs')) {
console.log('The substring is included!');
}string.prototype.includes is supported in ECMAScript 2015 and newer versions. For older versions, you can rely on indexOf or use the MDN Polyfill.
includes essentially functions the same as indexOf, but directly returns a boolean value without the need for the > -1 condition.
