If I have an input string with the value "testing the string", I want to create a function that splits each word and counts how many times each word appears in the input string.
The desired output should look like this: testing: 1, the: 1, string: 1
Thank you in advance for any help!
After breaking down the string, you can utilize the reduce function to tally the occurrence of each word
const text = "test test in string";
const output = text.split(' ').reduce((accumulator, current) => {
accumulator[current] = accumulator[current] ? ++accumulator[current] : 1;
return accumulator;
}, {})
console.log(output);Embrace the power of lodash with the following code snippet:
_.groupBy('analyze analyze this phrase'.split(' '))
You have the option to proceed in that manner.
let phrase = "testing testing testing in sentence";
let array = phrase.split(" ");
let output = {};
array.forEach(function(item) {
output[item] = (output[item] || 0) + 1;
});
console.log(output)I have a div with a maximum height and overflow set to auto. When the size of the div overflows, a scroll bar is automatically added. However, I have also set $("#itemsdiv").scrollTop(10000); so that the scroll bar is always at the bottom. Now, I want t ...
