Textual data is typically stored through sequences of characters - strings. These sequences, are ultimately, arrays, and converting between the two structures typically is both simple and intuitive. Whether you're breaking a word down into its characters, or a sentence into words - splitting a string into an array isn't an uncommon operation, and m...
The split() method is used to divide a string into an ordered list of two or more substrings, depending on the pattern/divider/delimiter provided, and returns it. The pattern/divider/delimiter is the first parameter in the method's call and can be a regular expression, a single character, or another string. For example, suppose we have a string: We...
The from() method from the Array class is the leading contender to the split() method. It's used to create an array, given a source of data - and naturally, it can be used to create an array from an iterable string: The major benefit of using Array.from() instead of split() is that you don't have to bother with setting a delimiter - the constituent...
The Spread Operator has several uses and is a widely-applicable operator in JavaScript. In our context - we'd be most interested in expanding arrays(strings are arrays of characters). The operator's syntax is simple and clean - and we can spread out the string into an array: The operator also works with UTF-8 emojis:
The Object.assign()method copies all values and properties of one object - and maps them to the properties of another. In a sense - it's used for cloning objects and merging those with the same properties: In our case - we'd be copying and mapping the values within a string onto an array: This approach is a bit more verbose, and less aesthetically ...
