You have to wait for TypeScript 2.0 with async/await for ES5 support as it now supported only for TS to ES6 compilation.
You would be able to create delay function with async:
function delay(ms: number) {
return new Promise( resolve => setTimeout(resolve, ms) );
}
And call it
await delay(1000);
BTW, you can await on Promise directly:
await new Promise(f => setTimeout(f, 1000));
Please note, that you can use await only inside async function.
If you can’t (let’s say you are building nodejs application), just place your code in the anonymous async function. Here is an example:
(async () => {
// Do something before delay
console.log('before delay')
await delay(1000);
// Do something after
console.log('after delay')
})();
Example TS Application: https://github.com/v-andrew/ts-template
In OLD JS you have to use
setTimeout(YourFunctionName, Milliseconds);
or
setTimeout( () => { /*Your Code*/ }, Milliseconds );
However with every major browser supporting async/await it less useful.
Update: TypeScript 2.1 is here with
async/await.
Just do not forget that you need Promise implementation when you compile to ES5, where Promise is not natively available.
PS
You have to export the function if you want to use it outside of the original file.
