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 = throttle(updatePreview, 500);
inputField.addEventListener('input', throttledUpdatePreview);

Kind: global function
Example
`js`
toArray('hello')

// returns 1.23
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]]
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);
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);
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
trims the beginning whitespaces from the provided string
Kind: global function
Example
`js`
trimStart(' hello')
// returns 'hello'
trims the end whitespaces from the provided string
Kind: global function
Example
`js`
trimEnd('hello ')
// returns 'hello'
returns the provided string repeated the specified amount of times
Kind: global function
Example
`js`
repeat(3, 'test')
// returns 'testtesttest'
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']
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]
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]
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]
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']]
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]]
