Question

"abc def"
"abcd efgh"

If I have a large string with a space that separates two substrings of varying length, what’s the best way to extract each of the substrings from the larger string?

Because this is a string rather than an array, array syntax s[0] will only retrieve the first letter of the string (‘a’), rather than the first substring.

Answer 1

Use the split method of the String object:

"abc def".split(' ')[0] // Returns "abc"

Works like this:

"string".split('separator') // Returns array
