Splitting strings by lengths
JavaScriptAll snippets in this category →
Posted on JavaScript can split strings at given characters. By matching against a regular expression, we can split strings into substrings of a given length instead.
// split at every `O`; all `O`s are gone in the result
"BRBIDKLOLOMGOK".split("O") // ⇒ ["BRBIDKL", "L", "MG", "K"]
// split into groups of up to 3 characters (the last group can be shorter)
"BRBIDKLOLOMGOK".match(/.{1,3}/g) // ⇒ ["BRB", "IDK", "LOL", "OMG", "OK"]// split at every `O`; all `O`s are gone in the result
"BRBIDKLOLOMGOK".split("O") // ⇒ ["BRBIDKL", "L", "MG", "K"]
// split into groups of up to 3 characters (the last group can be shorter)
"BRBIDKLOLOMGOK".match(/.{1,3}/g) // ⇒ ["BRB", "IDK", "LOL", "OMG", "OK"]// split at every `O`; all `O`s are gone in the result
"BRBIDKLOLOMGOK".split("O") // ⇒ ["BRBIDKL", "L", "MG", "K"]
// split into groups of up to 3 characters (the last group can be shorter)
"BRBIDKLOLOMGOK".match(/.{1,3}/g) // ⇒ ["BRB", "IDK", "LOL", "OMG", "OK"]// split at every `O`; all `O`s are gone in the result
"BRBIDKLOLOMGOK".split("O") // ⇒ ["BRBIDKL", "L", "MG", "K"]

"BRBIDKLOLOMGOK".match(/.{1,3}/g) // ⇒ ["BRB", "IDK", "LOL", "OMG", "OK"]
