Add line break inside string only between specific position and only if there is a white space JavaScript
We are required to write a function, say breakString() that takes in two arguments: First, the string to be broken and second, a number that represents the threshold count of characters after reaching which we have to repeatedly add line breaks in place of spaces.
For example −
The following code should push a line break at the nearest space if 4 characters have passed without a line break −
const text = 'Hey can I call you by your name?'; console.log(breakString(text, 4));
Expected Output −
Hey can I call you by your name?
So, we will iterate over the with a for loop, we will keep a count that how many characters have
elapsed with inserting a ‘
’ if the count exceeds the limit and we encounter a space we replace
it with line break in the new string and reset the count to 0 otherwise we keep inserting the
original string characters in the new string and keep increasing the count.
The full code for the same will be −
Example
const text = 'Hey can I call you by your name?';
const breakString = (str, limit) => {
let brokenString = '';
for(let i = 0, count = 0; i < str.length; i++){
if(count >= limit && str[i] === ' '){
count = 0;
brokenString += '
';
}else{
count++;
brokenString += str[i];
}
}
return brokenString;
}
console.log(breakString(text, 4));Output
The console output will be −
Hey can I call you by your name?
