toPairs() returns an array of derived from the provided object key-value tuples **Kind**: global function **Example** ```js toPairs({ a: 1, b: 2 }) // returns [['a', 1], ['b', 2]] ``` ## trailingThrottle() ensures that a function is executed at a fixed interval, so that it is not called too frequently **Kind**: global function **Example** ```js const updatePreview = () => { ... } const throttledUpdatePreview = trailingThrottle(updatePreview, 500); inputField.addEventListener('input', throttledUpdatePreview); ``` ## leadingThrottle() ensures that a function is executed at a fixed interval, so that it is not called too frequently **Kind**: global function **Example** ```js const updatePreview = () => { ... } const throttledUpdatePreview = leadingThrottle(updatePreview, 500); inputField.addEventListener('input', throttledUpdatePreview); ``` ## stringCompare() returns 0 for matching strings return -1 for string with lower char code at some position return 1 for string with greater char code at some position **Kind**: global function **Example** ```js stringCompare('abc', 'abc') // returns 0 stringCompare('abc', 'abd') // returns -1 ``` ## trimStart() trims the beginning whitespaces from the provided string **Kind**: global function **Example** ```js trimStart(' hello') // returns 'hello' ``` ## trimEnd() trims the end whitespaces from the provided string **Kind**: global function **Example** ```js trimEnd('hello ') // returns 'hello' ``` ## repeat() returns the provided string repeated the specified amount of times **Kind**: global function **Example** ```js repeat(3, 'test') // returns 'testtesttest' ``` ## uniqBy() returns an array with all the duplicates from the provided array removed based on the iteratee function **Kind**: global function **Example** ```js uniqBy(el => el.toString(), [1, '1', 2, '3', 3]) // returns [1, 2, '3'] ``` ## uniq() returns an array with all the duplicates from the provided array removed **Kind**: global function **Example** ```js uniq([1, 1, 2, 3, 3]) // returns [1, 2, 3] ``` ## update() updates the provided array with the provided value on the specified index **Kind**: global function **Example** ```js update(2, 3, [1, 2, 5]) // returns [1, 2, 3] ``` ## without() returns an array without the specified elements from the provided array **Kind**: global function **Example** ```js without([2, 4], [1, 2, 3, 4, 5]) // returns [1, 3, 5] ``` ## zipWith() returns an array of tuples of certain index elements from two provided arrays based on the zipper function **Kind**: global function **Example** ```js zipWith((a, b) => [a * 2, b.toString()], [1, 2, 3], [10, 20, 30]) // returns [[2, '10'], [4, '20'], [6, '30']] ``` ## zip() returns an array of tuples of certain index elements from two provided arrays **Kind**: global function **Example** ```js zip([1, 2, 3], [10, 20, 30]) // returns [[1, 10], [2, 20], [3, 30]] ```
