How can you extract a string from an array?

When attempting to loop through a string array in TypeScript, I encounter an error stating that foreach is not a function. What is the correct way to implement this in TypeScript?

Here is my code in main.ts:

content = ["renewal", "payments"]

If I use a for loop like this:

for (let i = 0, len = content.length; i < len; i++) {
    console.log(content[i]);
}

It prints all the indexes [r e n e etc]. However, if I attempt to use forEach like this:

content.forEach(function(content){
    console.log(content);
})

I receive an error indicating that content.forEach is not a function.

Answer №1

Looks like your code is working well, but there's a chance that you've modified the type of content somewhere in your code. Make sure that any functions you're using with content aren't changing the original array.

You could also try using more modern syntax, such as:

content.forEach(item => {
    console.log(item);
});

or even

content.forEach(item=> console.log(item));

Just a couple of small things to note; you don't need to store the length in a for loop (the JS engine takes care of that for you), and I'm not sure if it makes a difference, but you misspelled 'renewal' ;)
