JavaScript Reg Exp Not Working With matchAll

[John Weiss]

Trying to get all delimited items in a string.

Here's the code:

const myString = "abc{{HELLO}}defg{{WORLD}}"
const templateFieldsRegex = /\{\{\w+\}\}/g
const templateFields = myString.matchAll (templateFieldsRegex)

I expect to get array ["{{HELLO}}", "{{WORLD}}"]
Not getting any results.

Solution is to use `.match` instead of `.matchAll`.
.match gives an array.

.matchAll can give an iterable by using the spreader

const iter = [...templateFields]
